Food-at-home prices are up almost 30% since the start of the pandemic, and they are not coming back down. Other things have, but grocery rarely does. Once prices climb, they stay. The retailer has no pressure to bring them down because the shopper has no pressure to apply.
This is the cost of an information gap. Most families live within five miles of 10 to 12 grocery stores, but almost none of them comparison-shop. The ones who try are spending two to three hours a week recreating the same list across multiple retailer apps to see what each one charges. That is a part-time job for a piece of information that should take 30 seconds to retrieve.
What Stretch Actually Does
Stretch is a free mobile app, available on Apple and Android. The shopper uploads a list before leaving home. The app compares the full basket, not individual items but the total shop, across 28 retail chains and more than 25,000 store locations nearby. It shows what each store will charge, which store has everything, and which direction to drive.
Users are reporting savings of $20 to $40 a week, just from checking. No coupon clipping. No brand switching. No tradeoffs. Turning left out of your driveway instead of right is sometimes a $30 decision. Over a year, that decision adds up to more than a thousand dollars.
Behind the app is a serious data and AI lift. One of the hardest problems in grocery comparison is product equivalency: store brands and national brands are labeled differently across retailers, package sizes vary, and the same item can be priced 30 different ways across a single zip code. Stretch has built models that solve the equivalency problem at scale, mapping roughly 500,000 products so that a basket comparison reflects what the shopper actually intends to buy.
The Rule of Threes
The Stretch team has a simple operating principle for what to automate: if a shopper does something more than three times a week, the team builds the tool that handles it. That principle is why AI is embedded in the product without ever being announced as AI. The shopper sees a smart shopping list. The engine underneath handles advertising, onboarding, data organization, product equivalency, and the ranking of stores. Anything surfaced to the shopper has to be actionable. Nothing is shown for its own sake.
A Wedge Into the Future of Commerce
Grocery was famously late to e-commerce. It may turn out to be early to agentic commerce. The reason is simple: groceries are the most repeatable purchase the average household makes. Roughly the same list, every week. That repeatability is exactly the conditions an AI shopping agent needs to be useful. The household that gets used to handing its grocery list to a trusted assistant today is the household that will hand off other categories tomorrow.
Walmart has Sparky. Amazon has Rufus. For the 90% of households those platforms were not designed to fully serve, you have Stretch. The grocery industry has operated comfortably inside an information gap for decades. Stretch is closing it, one shopping list at a time.
