Discounts with Cartwheel

Do you know about Targets Cartwheel app? Im sure by now most people know what it is, but if you download Cartwheel app on your phone. And when you shop at target, you just show the employee your app code when checking out and you will get a discount. So basically how the app works is that It gives you percentages off on certain items.
This is actually really cool because if you use coupons or find something on sale, plus there is a cartwheel offer, its an even lower price for you! So check it out! I found A discount on the app for childrens shoes this week. So check them out!
