Lord of the Rings Online 60 Day Time Card
It worked after 5 years on the shelf at the store!
I canceled my credit card, so I needed some way to pay for my lotro vip subscription. I went to my local gamestop, where the clerk had to go into the back and find one of these game cards. He said they've been on the shelf since 2007. It even said Shadow of Angmar on it! I used cash to buy it, and it worked fine even after 5 years! I was psyched. It was a little confusing to use it, because you don't enter the code in the product code field on the account page, you have to navigate to a page that's specifically for game cards. Once I found that I put it in and it worked fine. And yes, I got my 500 TP still.
