Does Where You Shop Matter? 727 Recipes Say: Sometimes
The short answer
Store choice matters far less than recipe choice, brand tier, or how you collect the groceries - until you change banner tiers, where it matters a lot. Within one chain, our data puts the median gap at $0.15 per serving. Across chains, external surveys put discount grocers 20 to 40 percent below the average store.
This post is the synthesis of the Compare series. Each number below was measured, either by pricing real baskets item by item at real stores or by a named external survey. Nothing is a vibe about which store "feels" cheap. The point is to rank the decisions by dollars, so you spend effort where the money is.
What we measured, and what we borrowed
Our own data covers one chain deeply: 727 recipes fully priced at two Kroger stores in one metro, 6,470 comparable ingredient lines, 163 store-brand versus name-brand pairs, and one median basket run through in-store, pickup, and delivery pricing. For breadth across chains, we lean on an external survey and label it clearly.
That split matters for honesty. We can tell you precisely what happens between two stores of the same banner, because we priced it line by line. We cannot price an Aldi, so for cross-chain gaps we cite Consumers' Checkbook's national supermarket survey, updated November 2025, which shopped a 150-item basket across seven metro areas.
Within one chain, location is a rounding error
The same recipe at two stores of the same chain usually costs nearly the same: a median difference of $0.15 per serving across our 727 paired recipes, with a third of recipes identical to the cent. Summed over every basket, the cheaper store won by just 2.1 percent - $20,496 versus $20,929.
The reason is that shelf pricing is essentially centralized: 99.2 percent of the 778 products picked at both stores carried the exact same price, and the handful of exceptions were perishables like milk, eggs, and bananas. The full line-by-line breakdown is in our two-store comparison.
Direction was not even consistent. One store was cheaper on 298 recipes, the other on 181, and 248 tied exactly. There was no "cheap store" to find - just noise around a small tilt. Driving across town to the other location of your chain is, on the median dinner, a fifteen-cent decision.
The exception: assortment, not pricing
When the same recipe did cost meaningfully more at one store, the cause was almost never a price tag. It was which products the store stocked. Among recipes differing by $1 or more per serving, a single ingredient line explained a median 86 percent of the whole gap.
The worst case in our data swung $6.03 per serving because one store's cheapest suitable lettuce was $2.29 iceberg and the other's was $4.79 romaine hearts, multiplied by the eight units the recipe needed. Same chain, same week, one vegetable. Expensive recipes swing hardest: the over-$8 tier had a 90th percentile gap of $1.31 per serving, while sub-$3 recipes differed by a median of a nickel.
Across banners, the gaps get real
Cross-chain price differences dwarf within-chain ones. Consumers' Checkbook's national survey, updated November 2025, shopped a 150-item market basket in seven metro areas and found Aldi 30 to 40 percent below the all-store average, Lidl about 20 to 25 percent below, and chains like Walmart, WinCo, and Market Basket typically 12 to 30 percent below.
Checkbook's arithmetic on what that means: for a family spending $300 a week, a 10 percent price difference totals $1,560 a year, and a 25 percent difference nearly $4,000. Those are survey figures for a fixed basket, not our own pricing runs, so treat them as the scale of the effect rather than your exact number.
Note what changes across banners: private-label programs, sourcing, and assortment all differ, so the identical-price finding from our two-store data does not carry over. Banner choice is a genuinely different product mix, which is exactly why it moves real money when a same-chain transfer does not.
Brand tier travels with you
The store-brand decision moves more money than the store-location decision, and you make it inside whatever store you already use. Across 163 matched pairs at one Kroger, the house brand was cheaper 91 percent of the time, by a median of 32 percent per unit.
Scaled to a basket: store brands carried 63 percent of the dollars in our median $24.85 four-serving basket, and swapping those lines to name-brand equivalents would add roughly $7. That single habit is worth about 45 store-transfer medians. The tier details - and where the house label loses - are in the store brand versus name brand data.
This is also a big part of what makes discount banners cheap: their shelves are overwhelmingly private label. Some of the Aldi gap is available at your current store by reaching one shelf lower.
Fulfillment can cost more than any store gap
How you collect groceries changes the bill more than which store sells them. The same $24.85 basket is $24.85 in-store, about $29.80 through pickup below the commonly reported $35 minimum, and $39.56 through third-party delivery at the 23 percent markup a 2025 Groundwork Collaborative and Consumer Reports investigation measured, plus a fee and tip.
That is a 59 percent spread on identical food - triple the biggest banner gap in the Checkbook survey - and it is the easiest one to switch off. The mechanics are in the pickup versus delivery comparison and the delivery markup breakdown.
Ranking every lever we have measured
Put the four store-shaped decisions beside the one kitchen-shaped decision and the ranking gets blunt. Recipe selection swings dollars per serving. Fulfillment and brand tier swing dollars per basket. Banner tier swings a large percentage. Same-chain location swings cents. Here is each lever with its measured size, on comparable terms.
| Decision | Measured effect | On a $24.85 basket |
|---|---|---|
| Recipe choice | $0.41 to $46.84 per serving across 712 priced dinners | the basket itself |
| Banner tier (e.g. Aldi vs average) | 20-40% (Checkbook survey, 150-item basket) | $5 to $10 |
| Fulfillment model | $24.85 in-store vs $39.56 marked-up delivery | up to $14.71 |
| Brand tier at your store | 32% median per-unit gap, 91% of 163 pairs | about $7 |
| Location within a chain | median $0.15/serving; 2.1% across 727 baskets | about $0.50 |
Sources: CentsPerServing corpus pricing at two Kroger stores, July 2026 (recipes, brands, fulfillment baseline); Consumers' Checkbook national supermarket price survey, updated November 2025 (banner tier); Groundwork Collaborative with Consumer Reports, 2025 (delivery markup bound). Basket-level effects are arithmetic applications of the measured rates.
The table is the whole argument. The two decisions people argue about most - which store, which location - sit at the extremes of the ranking depending on whether a banner change is on the table. The three decisions in the middle are available today without changing where you park.
A decision framework that survives the data
For staple cooking - beans, rice, pasta, canned goods, frozen - shop wherever is convenient. Those categories priced almost identically between our stores, and sub-$3 recipes differed by a median of five cents a serving. The cheap tier of our 712 priced dinners is effectively store-proof.
Three situations justify caring about the store. First, a banner-tier switch: if a discount grocer is on your route, the external survey evidence says the gap is 20 to 40 percent on comparable items. Second, specialty-ingredient recipes: 21 percent of our recipes differed by more than 10 percent of their own cost between stores, concentrated in dishes needing an item one store stocks cheaply. Third, any recipe already over $8 per serving, where store gaps run largest.
Everything else is bigger inside the store than between stores: pick the recipe by cost per serving, take the base house label on interior aisles, and clear the pickup minimum instead of paying delivery's fee stack.
What this data cannot tell you
Honest limits: our two-store comparison covers one chain in one metro, so it measures location effects, not chain effects. We have not priced a discount banner ourselves, which is why the cross-chain numbers are attributed to Checkbook's survey rather than our own baskets. And every shelf price here was captured in July 2026; prices move without notice.
Survey baskets and recipe baskets also measure slightly different things. A fixed 150-item basket weights categories by the survey's list; a recipe basket weights them by what dinner actually needs. Both are useful, but neither is your receipt - which is the strongest reason to price your own list at your own store rather than trust any average, including ours.
Run the comparison for your own store
Every first-party number above came from the same engine you can use directly: paste a recipe into the recipe pricer, pick your store, and read the line-by-line basket. Change the store and the diff tells you whether your dinner is in the store-proof tier or the store-sensitive one - before anyone drives anywhere.
For a full week, the week builder prices the combined list with package math at your store, which is where the real money is anyway. The rest of the Compare series holds the deep dives behind each row of the table above.

Which grocery store is cheapest?
Across chains, discount grocers win by a wide margin: Consumers' Checkbook's national survey, updated November 2025, found Aldi's prices 30 to 40 percent below the all-store average and Lidl about 20 to 25 percent below, with Walmart, WinCo, and Market Basket typically 12 to 30 percent below. Within one chain, our 727-recipe data shows location barely matters.
Does it matter which location of a chain you shop at?
Rarely. When we priced 727 recipes at two Kroger stores in the same metro, 99.2% of shared products carried identical shelf prices, the median recipe differed by $0.15 per serving, and the totals across all baskets differed by 2.1%. A third of recipes cost exactly the same to the cent.
Is it worth driving to a different store to save money?
Within one chain, usually not: the median gap of $0.15 per serving means a week of five family dinners differs by about $3, which gas and time consume. Switching banner tiers is different - moving regular shopping to a discount grocer can cut a basket 20 to 40 percent per external surveys.
What saves more money than switching stores?
Three levers we have measured all beat within-chain store choice: recipe selection (our priced dinners span $0.41 to $46.84 per serving), brand tier (store brands ran a median 32% cheaper per unit, roughly $7 on a $25 basket), and fulfillment model (the same basket cost $24.85 in-store versus $39.56 via marked-up delivery).
Why do some recipes cost much more at one store than another?
Assortment, not pricing. Identical products almost always cost the same within a chain; the gaps appear when one store does not stock the cheapest suitable product for an ingredient. Among recipes that differed by $1 or more per serving in our data, a single ingredient line explained a median 86% of the gap.
How much does delivery add compared to shopping in-store?
Our median four-serving dinner basket was $24.85 at the shelf. Retailer pickup below the order minimum turned it into about $29.80 with the commonly reported $4.95 fee. Third-party delivery at the 23% markup measured by a 2025 Groundwork Collaborative and Consumer Reports investigation, plus a fee and tip, reached $39.56.
How much do store brands save at the same store?
Across 163 matched pairs at one Kroger store, the house brand was cheaper in 91% of cases by a median of 32% per unit. Scaled across the store-brand share of a median $24.85 basket, switching those lines to name brands would add roughly $7 - more than most store-to-store gaps.
How did you measure whether store choice matters?
We priced the same recipes ingredient by ingredient at two Kroger stores using each store's own catalog, shelf prices, and package sizes, rounding package counts the way a checkout does. Only recipes where every non-pantry ingredient priced cleanly at both stores count - 727 recipes and 6,470 ingredient lines in July 2026.
Data: CentsPerServing corpus pricing runs, July 2026 - 727 recipes fully priced at both Kroger store 01400513 and store 01400421, 6,470 comparable ingredient lines, 163 store-brand versus name-brand pairs, and 748 fully matched dinner baskets, all item-level shelf prices with package-count math.
