Which is such an easy thing. So why do so many people get it so very wrong?
I have a used Wal-Mart card in my wallet right now, for instance. I don't know exactly how much is left, but because they just work, knowing that it's *about* $10 is good enough. In fact, having no idea is good enough, so long as I bring enough money to buy my stuff if it turns out to be empty. All gift cards *ought* to work that way, and while I know at least some of the good reasons that they don't, it doesn't make it right, nor does it make it something that people should know about without being told.
