QUICK ANSWER
For this week’s sales across stores, a flyer app such as Flipp. For prices at several nearby stores in one place, a delivery marketplace such as Instacart, remembering its prices can sit above in-store prices. For the exact shelf price, the store’s own app (Walmart, Kroger, Target). For money back after you shop, a cash-back app such as Ibotta.
The five types, side by side.
| Type | Examples | What the price is | Best for |
|---|---|---|---|
| Weekly flyer apps | Flipp | Advertised sale prices from weekly circulars | Planning meals around what is on sale |
| Delivery marketplaces | Instacart | Prices on the platform, which may include a markup over in-store | Comparing several nearby stores at once, and delivery |
| Store apps | Walmart, Kroger, Target | That chain’s own current price at your store | Accurate prices and digital coupons at one store |
| Cash-back apps | Ibotta | Rebates credited after you buy eligible items | Lowering the bill without changing stores |
| Clearance apps | Flashfood, Too Good To Go | Discounted near-date or surplus food | Big discounts if you can be flexible |
App features and availability change often; we checked these categories in October 2026. Always confirm a price in the store’s own app before relying on it.
Weekly flyer apps.
Flyer apps gather the weekly circulars that chains publish and let you search across them: type “chicken thighs” and see which stores advertise them this week. They are the fastest way to plan a week around sales. Their limit is that they show advertised promotions, not every shelf price, so an item that is not on sale may not appear at all.
Delivery marketplaces.
Marketplaces like Instacart list many stores in one app, so you can look up the same product at several of them. That makes them the most convenient cross-store view. Prices on a marketplace can be higher than in the store, and service and delivery fees apply at checkout, so compare the final total, not the item price.
Store apps.
A chain’s own app shows its price at the store you select, plus digital coupons and loyalty prices that marketplaces may not show. The trade-off is obvious: one app per store, and no comparison between them.
Cash back and clearance apps.
Cash-back apps credit you after you buy eligible items, so they stack with whatever store you choose. Clearance apps sell near-date or surplus food at a discount, often a large one, in exchange for flexibility on what and when.
The step before comparing prices.
Comparison only saves money on a list you were going to buy anyway. The bigger saving is usually the list itself: planned meals, no duplicates, and pack sizes that match what you will cook. Set a target with the grocery budget calculator, price the list with the grocery cost estimator, and see grocery list apps for keeping it shared.
Common questions.
Is there an app that compares grocery prices between stores?
Several, in different ways. Flyer apps compare advertised sales across chains; delivery marketplaces show platform prices at several stores; store apps show one chain’s exact price. None covers every store and every price.
Are Instacart prices the same as in the store?
Not always. Some stores set higher prices on the platform, and fees are added at checkout. Compare the final total with the store’s own app for important purchases.
What is the best free grocery price comparison app?
For weekly deals, Flipp is free. Store apps and cash-back apps are free too. The best choice depends on whether you want sale prices, exact shelf prices or money back.
How can I compare a whole list, not one item?
Price the list item by item in the store app you use, or get a quick benchmark from our cost estimator, which totals real Walmart prices recorded in September and October 2026.
Compare less, plan more.
MealPot plans the week and writes the list, so the price you compare is for food you will actually cook.
