Don't you hate it when...

Don't you hate it when you go somewhere and they won't take your coupon. Happened to me today at CVS. The part that sucks is, it totally threw me off my game and I forgot to use my coupon for spending over $20 so I could get $4 ecb back and then I forgot to use my giftcard. So I trip that should have cost me next to nothing cost me $4. Ughh I hate it when that happens.
