PlayStation 3 owners will soon be able to buy PlayStation Plus membership at retail, with gift cards granting access to Sony's premium PlayStation Network now deploying to stores in North America.
A Kotaku tipster informs us that cards have already arrived at Target stores in the northeast, at least in designations of $17.99 USD for three months worth of PlayStation Plus access. Sony also offers a 12 month long subscription option priced at $49.99 USD. Currently, the subscription based service allows early access to some demos and beta tests, discounts on software and the occasional freebie.
Thanks to maxdivision for the tip!
