Do GameStop reward certificates expire? Some people might think so, based on the fact that some GameStop stores have been selling them for a few weeks now. But according to a recent report from The Verge, not all GameStop stores are doing this. In fact, some stores are still selling them without any expiration date. This is strange because it seems like a lot of people were upset when they first started seeing these certificates in store. Some people thought that they were just a way to get free games, but now it seems like they may not be as valuable as they once were. It’s possible that GameStop is just giving them out to customers who have been buying them regularly, but it’s also possible that there is an expiration date on these certificates. We’ll just have to wait and see what happens.
