A lot of folks didn't get to play their PlayStation 4 during Christmas and Sony's looking to make it up to you.
This weekend, there will be a one time 10% off code for one item (with some exceptions) for PSN members. The code is valid from 9:00 AM 1/23 PST through 9:00 AM PST 1/26.
In addition, people should be getting an extra 5 days tacked on to their subscription. If you qualify, you'll be getting an email to let you know. You won't have to do anything, just enjoy the extra 5 days.
