It says right on all the of the coupons I have something like, "Not valid for prescriptions previously filled at a CVS pharmacy". Meaning if you filled it there two months ago, transferred it to Target last month, and are now transferring it back to get the gift card, you can't do that. I can't say that I blame them--can we really expect that they'll continue to just give stuff away? They're trying to make money, too!
