HOUSTON (KTRK) -- The use of digital coupons has exploded in recent years and www.letstalkpayments.com has the six top mobile tools that make it easy for shoppers to save money on groceries and other everyday expenses.

Here are a few:

Checkout 51: Receive cash back on grocery purchases ranging from condiments to almond milk to fresh produce with Checkout 51. Like Walmart's Savings Catcher, Checkout51 requires users to upload a receipt image as proof of purchase. Users then select eligible items from Checkout 51's rotating list of offers and receive cash back for their purchases. Once a user's credit reaches $20, they will receive a check in the mail.

Target Cartwheel: Target shoppers can save more on their weekly hauls with the Cartwheel app, which offers rotating savings on everything from food to apparel to home goods. New users can redeem 10 offers per transaction and earn additional deals the more they use the app. There are many insider secrets to optimizing savings on Cartwheel, including the fact that deals can be combined with manufacturer coupons, rebate offers and Target's 5% REDcard discount for additional savings.

Coupon Sherpa: With families increasingly buying grocery items from specialty retailers and dollar stores, a mobile coupon app like Coupon Sherpa can help save an additional 10 to 20%.
