No, the Edge card itself does not expire. Meaning that if you trade games in and put money on that card, it is yours forever*.
The subscription to GameInformer is a year long, and must be renewed every year.
This also applies to the Edge Discount of 10% off used games/accessories and strategy guides.
*=If the government doesn't declare it lost property and take the money.

how i get my edge card from gamestop
gamestop
No but the credit can expire.
120 months they expire
No. They are not the same but you can buy app store gift cards at gamestop.
It depends on the Gamestop. Some will buy Pokemon cards, but some won't.
Afraid not my friend. The GameStop Edge Discount card is only good in GameStop/EB Games stores or online at GameStop.com
Unfortunately no. The reason is that the credit stored on an Edge Card is not taxed. This is because money put on an Edge card is from trading games in at a GameStop location. Since the games are traded for in-store credit, the government does not own this "currency", thus it is not taxed. GameStop does sell gift cards, which are essentially the same, except taxed.
All Credit cards
Some cards expire, but some do not. On the paper it was glued on to, it should say, or on the back of the card.
You can use them to buy games or whatever they have at GameStop
