Might want to use it very soon . . .
We took our gift card and tried to use it up about a month ago when rumors of this were first circulating.
When we checked out we had spent around $20 and came to find out we only had $1.70 left on that stupid card.
False economy! We could have gotten the same book on Amazon for $10 with shipping and not wasted the time and fuel driving out there.
You probably had one of those cards that "devalued" if you didn't use it right away. I remember hearing about gift cards from all kinds of retailers that lost value unless you used it within a certain amount of time. It was probably stated in the super fine print. I might be wrong but I think that it is illegal for new gift cards to do this now.
