Naw that just pokes the lion. The fail proof way and very easy to do is go out and buy yourself a wallet with lots of slots for credit cards, count the number of slots then go buy that many gift cards from places she shops. The one I purchased last year had twelve slots so I filled all slots with 100 dollar gift cars and wrapped it up in the money are I also put bills of every denomination. She opened the gift smiled at the wallet and told me it was a mans wallet then opened it nd started to laugh she removed all the cars and the money and handed me the wallet back. I received the wallet I wanted but had nothing to put into it. This year I bought a card holder (hard case) and filled it. I tell you this is a WINNER guys.
