Today is Black Friday, and while usually online purchases are reserved for Cyber Monday, there are some good ones available today as well. One of the best is at Best Buy, where they are offering up a $29.99 PlayStation Plus 12-month subscription card. The card usually goes for $50, so saving $20 is a great thing. Groupon had a similar offer earlier this morning, but sold out quickly. If you want to add on another year to your subscription for your PS3, PS4 and Vita, the time to buy is now.
