Frustrated at Target

I was all excited this morning, because I had a great deal lined up at Target for Pamper's diapers and wipes, using manufacturer's coupons and Target's web coupons, on top of a sale. I found out about it on http://www.moneysavingmom.com/, which linked me to http://www.afullcup.com/ , where I printed the coupons. Anyway, I got there and at the checkout found out that they are not accepting any of their web coupons anymore, because of some counterfeit ones that are circulating around. Stinky!!! I would have gotten two packs of diapers, good ones, and two packs of wipes for next to nothing! One cheater spoils it for the rest of us!
