It looks like Steam vouchers are definitely headed to GameStop. Images sent to Joystiq by an anonymous tipster reveal an in-store display for Steam Wallet voucher cards in both $20 and $50 amounts. This bolsters the image that made the rounds last week, providing further evidence that the cards will indeed be going on sale at GameStops very soon.

The upshot of all this, of course, is that GameStop will be selling gift cards for one of its major competitors, which is especially intriguing as the company has been working to build its own digital distribution platform for several years. We've contacted GameStop and will provide updates as this story develops.
