GameStop continues its march toward the Store of the Future, by offering PSN content both in-store and (soon) online. The retailer started offering Xbox Live DLC in-store earlier this year.

According to Sony and GameStop, cards for PlayStation Plus subscriptions, PSN games and add-on content will be available in 4,400 GameStop stores this month, and will also be available through GameStop.com. Not only is this a way for GameStop to get a piece of the exploding digital distribution market, it's a much more elegant way to gift a specific game, we suppose, than just writing "Scott Pilgrim" in Sharpie on a $10 PSN card.
