Have you heard about Favado?
It's my new fave shopping app. It not only lists my stores deals/ads, but it also will let me know if there are coupons for those items! Simply add the items to your list, then email it to yourself and you can view all the printable coupons available, and head off to the store. This is a great deal for when you price match at Walmart. Maybe you find something you like, but you want to know if there's a better price. You can do that with Favado!
