GameStop confirmed to Joystiq today that the will start carrying Steam Wallet cards tomorrow.

“We are currently the only retailer with it,” Steve Nix, manager of PC digital distribution for GameStop said.

The deal has been a work in progress, according to Nix. However, he did add that the company plans to keep pushing Impulse as well.

“Really, this doesn’t affect anything we’re doing with Impulse,” Nix said. “We doubled the PC download business with the Impulse technology we acquired. We’re happy with that. We’re now online over 1600 SKUs, we’ll continue to grow that and continue to invest in that.

“We’re just offering options for customers. This in no way changes our investment or what we’re doing with that business.”
