Starting today you can purchase Steam Wallet codes at GameStop stores. These codes, which are available in $20 and $50 denominations, can be added to a Steam account and used to purchase content through Valve's immensely popular digital distribution service. This move may come as a surprise to some as GameStop last year purchased Steam competitor Impulse, yet it actually is a very sensible move for both sides.

For GameStop, this is another way for it to insert itself into the sale of digital content. It already offers things like downloadable content and points for the console manufacturers' respective platforms, as well as (more recently) digital PC games through Impulse. Getting a cut of money spent on Steam is an obvious benefit, but there is more to it than that.
