PlayStation 3 owners should be happy to hear that you’ll soon be able to purchase PlayStation Plus membership cards at retail, as gift cards granting access to Sony’s premium PlayStation Network are now being shipped to stores in North America. The cards have already arrived at some Target stores and will set you back $17.99 for three months of PlayStation Plus access, though Sony also offers a 12-month long subscription for $49.99. The service currently allows users early access to some demos and beta tests, discounts on software and the occasional free gift.
