PowerUp Rewards has always been hugely screwed up for me.
I got the free card, made an account on PowerUpRewards.com and went to activate my card, but for the span of about a week, it kept telling me there was some kind of activation error.
Now after seeing this, I log in to my PowerUpRewards account and try to activate the same card, and it tells me the number has already been activated. So I go into my Gamestop.com account and try to merge it with my PowerUpRewards account, and it tells me I can't because I entered the same account information twice.
I'd like to buy the Ratchet & Clank and Jak & Daxter collections, but I give up.
