I recently bought a $10 PSN Wallet Code from Amazon.com. I've bought many other things from there before, including Sly Cooper 4 and a 1-Year PS+ subscription. Both codes worked fine. But when I enter the code either on my PC or on my PS3, both will give me an error saying the code is invalid or can no longer be used. Anybody else having the same issue? I had this issue when redeeming my PS+ subscription on black friday, but I haven't heard of any recent similar outages.
