If you have $100 to spend on PSN, go right ahead on do just that. Buy PS Plus or something, because when you do, Sony will credit your account with $20 as part of its October PSN promotion. Deal or no deal?
Also, any and everything you purchase on the store will count towards your $100 spent – that’s why I’m urging you to get PS Plus if you don’t have it already – even preordering games count towards the deal. Shoot, even signing up for Direct TV NFL Sunday will count.
Once you arrive at your hundred bucks spent mark, Sony will notify you in November via email and through a PSN message.
