Sony is running a limited time deal on Playstation Plus, offering an extra three months for free when you purchase a year membership.
The three added months provides added time to take advantage of the premium service's popular Instant Game Collection. The feature provides free access to a revolving door of PS3 and PS Vita games, with downloaded titles remaining in your personal library as long as you're a member.
The offer also extends to those who have made any recent PS Plus PS3 bundles – as long as the voucher is redeemed during the promotional period. Those who already have memberships can stack an extra year on to take advantage of the promotion as well.
The promotion goes through March 4th, and apparently is limited to North America.
