Grocery shopping is an unavoidable part of life. After all, where else are you going to find frozen pizza for those long nights of important business (ahem… Netflix) to take care of?

If groceries are a weekly staple, then it’s helpful to be armed with some savvy-shopping skills. Cash back apps are one of the easiest ways to cut down on food costs. By offering discounts, rebates, and other rewards, you can save hundreds when stocking your pantry.

Curious to join the fun? As smart shopping experts, our team at RebateKey knows how to navigate the grocery aisles. Check out our picks for the best cash back grocery shopping apps.

Grocery Rewards—How They Work

If you’re new to cash back apps, don’t worry. Let’s break down the ins-and-outs of a typical grocery rewards program.

Cash back apps are a win-win for customers and stores. Sellers get extra business through offering exclusive deals, while buyers pocket their savings on discounted purchases. Tapping into this on-demand resource can save you time and money at the grocery store.

So, how do you save money with a cash back reward app? Most programs give a few methods for earning rewards points or cash rewards, including:

  • Specific item purchases – Apps will designate store items to buy for rewards, granting the bonus points or value post-purchase.

  • Proof of purchase – With uploaded or automatically transferred receipts, you can earn cash back on your shopping trips.

  • Location visitation – Certain apps reward you just for stepping inside a store. Earnings tend to be low for this action, but every point counts.

  • Tasks & missions – A zero-purchase option, tasks like watching an advertisement or answering a poll can earn you free points.

Depending on the app, your accumulated points can turn into gift cards, direct payment, or store vouchers. After that, it’s up to you how to spend your savings.

Remember to pick the best grocery cash back app for you. Time, shopping preferences, and store locations are all important factors to consider for a grocery shopping app.

  • Easy mobile access
  • Seamlessly integrates with store membership cards


  • In-store purchases only

Secure, Safe Shopping

Privacy issues are more prevalent than ever. Everything from social media to news sites mine the personal data of their visitors.

With cash back apps, it’s important to choose secure and safe portals. Our above list includes only verified reward programs—no scams or identity theft. But if you look at other apps, keep these safety standards in mind:

  • SSL certification – Promises that all user app data is encrypted
  • Sensitive information – Never requires your SSN or bank account information
  • Account creation – Sets up a username, passcode, and payment account for each user
  • Recruitments – Zero enforced member recruitments or referrals
  • Payout time – Payout or rewards granted within a certain amount of days
