Best Buy has a deal on PSN credit and Playstation Plus that is almost impossible to walk away from. They are currently selling $20 worth of PSN store credit with three months of Playstation Plus for a total of $28.
Three months of Plus normally costs $17, so this is a savings of about $10. Not a bad deal if you’re looking to re-subscribe to Plus anyway. As always take advantage of this deal while it lasts.
