I redeemed some points for Microsoft gift cards. Mainly waiting for a sale to come up for some games I am looking at. I figured I would redeem them while I can before prices increase, only to then discover that the currency has an expiration date? Shouldn't this effectively be like money, how on earth is it allowed to expire?

I find it especially surprising since I live in Canada where the law generally does not allow gift cards to expire. So has Microsoft just found some way to bypass these laws or something like that?
