I've been given a load of Google Play gift cards from a family friend. You can guess what happened, it was pretty sophisticated but they realised in time. ("Google Play" is a meaningless term to them)
I don't really know what to do with these cards - I certainly can't use all of them. Ideally I just want to liquidate them to pay the money back, but there doesn't seem to be a good way to do that.
Any ideas? Does anyone have a use for them?
