2. Simplified comparison shopping

A handful of apps make it easy to compare prices and weekly sales across multiple stores. Basket, a crowd-sourced app, works by having users report on prices as they shop, providing prices from 170,000 grocery and retail stores. Simply put your grocery list into Basket and they’ll tell you where that list of groceries will cost the least. Basket will also pull in any coupons that apply, for additional savings. “Users can save an average 28 percent, before any coupons,” says Basket’s co-founder, Andy Ellwood.

Apps such as Favado and GroceryPal show weekly sales and special offers at stores on items you select, letting you compare deals. Both apps pull in available coupons that may lower the prices even more.

3. Getting you cash back

No time to comparison-shop? You can still get cash back after leaving the store, simply by scanning your receipt into rebate apps such as Ibotta or Checkout 51. With both apps, you can browse available rebates before, or after, you shop, submit a picture of your receipt (or product bar code). The apps calculate rewards you’ve qualified for, and deposits the money into an account you create on the app.

“I actually don’t look through the app until after I shop,” says Malisa Lieser, a family meal-planning consultant in metropolitan Minneapolis. “That way, I’m not buying things just because they have a rebate, but rather saving on items that were already on my list.”

4. Jogging your memory

Groceries have started using in-store Bluetooth transmitters and other tracking technologies to deliver personalized messages, based on information about a user’s location transmitted by their mobile phones. If you use a shopping or recipe app (with location services enabled), you may see messages popping up on your phone—from the store or brand sponsors—alerting you to sales, delivering coupons, suggesting a recipe, or giving you a heads-up about the special display that’s right in front of you.

David Eyler, a financial planner in Vermont, keeps his shopping list in an app, which he’s set with his local grocery store’s address. “I’m automatically reminded to stop at the grocery store and pick up items on my lists when I drive near its location,” he says.

5. Streamlined checkout

Amazon is exploring hybrid grocery store models that combine the seamless convenience of online shopping with a brick-and-mortar store.

In 2016, for example, the company launched Amazon Go, its first brick-and-mortar grocery store, in Bellevue, Washington. As customers enter the store, they are logged-in with their phones. Sensors track what items they take from the shelf. And as they walk out the door, their bill is automatically tallied and charged to their account.

Other retailers are experimenting with ways to speed checkout, with apps that let shoppers scan items, and compare prices, as they add them to the their cart, pay online, and show a QR code receipt at the door. In 2010, the Kroger supermarket chain started using QueVision, a system of sensors and predictive analytics to anticipate when customers are about to crush the checkout lines, sending in additional cashiers and helping to cut average wait time from four minutes to less than 30 seconds.
