Hi Diana, like Felix the Cat said but to be a little bit more descriptive, the circle is like Targets way of giving you offers back by entering your phone number anytime you're purchasing "in store" or even through the Target app "as long as you're logged in." It's pretty nice because for certain items you have bought they keep track of and will give you special offers on those items. It's "coupons" plus keeping track on your own behalf of all of the savings you can get.
Coupons. Basically.
