Following last month's successful promotion, Sony is running a similar "spend X, get X credit" deal on PlayStation Network this week.
The promotion includes anything purchased with your wallet on the PlayStation Store, meaning you can buy games, movies, or TV shows and be eligible for the credit. Simply spend $60 on PSN from now until November 26th, and you'll earn a $10 bonus.
This offer coincides with the launch of additional "PS3 Ultimate Editions," full retail games that are bundled with DLC. You can see the entire list on the PlayStation.Blog.
