If you spend $100 or more on the PlayStation Store in October, you will recieve a $20 credit to your wallet to spend in November! This is a store-wide promotion, so anything you purchase using your wallet will count towards the $100 total. One caveat: the credit back is limited to the first $100 you spend.
With great new programs like PSN Day 1 Digital, offering day-and-date digital PS3 games on the same day they hit retail, there are plenty of ways to participate in the “Buy $100, Get $20” promotion. As a reminder, PlayStation Plus members receive an additional 10% discount on a number of titles in the line-up when they pre-order. Additionally, if you’ve already pre-ordered one of the awesome titles in the PSN Day 1 Digital program, the money you’ve spent on those will count toward your $100 for October.
