When it comes to online purchases, you can simply open a new tab, type in ‘promo code’ and find a bunch of budgeting apps overflowing with promo codes.

But for offline shopping like groceries, can tech help you save money? You bet!

For most families, groceries are the second largest expense in the budget. It’s no surprise that saving on groceries is one of the first places that many people go to save a little extra cash. However, it can feel a bit tricky, as no one wants to deprive their family of food to save money! Thankfully, technology has made this a bit easier; some apps can help you save money or will pay you to shop. There are also many buying guides, such as this one for cheap earphones. Check out our list of the four best grocery savings apps.

Grocery IQ

Grocery IQ is a powerful shopping list app that allows you to make a list from the millions of items in the database. If you don’t want to search through the database, you can add items through bar code scanning or voice recognition. The app also offers coupons and has features that help you save money, making this a must-have tool for families that are short on time and money.

Ibotta

Ibotta offers thousands of rebates that are redeemable at over 50 retailers. Shoppers skim through offers by category and complete certain tasks to have a pending rebate added to their account. Duties involve things like watching a video or answering questions about your shopping preferences. Once you buy the item, upload a copy of your receipt and scan the UPC and the money is available for you to send to PayPal whenever you want it. Bonus offers and team offers can also help shoppers to boost the cash they get back considerably.

SnipSnap

SnipSnap is first and foremost a coupon app, and users can search thousands of coupons that are already online. Unlike other apps, you can also take pictures and upload print coupons to use in-store, eliminating the need to clip coupons or bring them with you. Only available for iOS.

SavingStar

SavingStar allows you to make better use of all of those store and loyalty cards. When you use a card or coupons, the savings are applied to the SavingStar account and converted to cash. Withdrawals are possible after you earn $5. For those who wish to give back, you can donate the money you receive through the app to individual charities.

One reason that these apps are so powerful is that they rely on things that you probably do already, like writing a list, or signing up for rewards programs, or using coupons. These apps don’t replace those ordinary activities, but instead, make them more efficient and increase their earning power leaving more time and money for you and your family.
