Wow make sure you sign up for the Best Buy mailing list. You receive a respectable number of mailings.
A big reason for me to do it is you receive messages about flash one day or less sales.
Saturday I received an email about 2 game titles on rediculous sale price.
One of the games I was not interested in but the other I had been on the fence about buying.
The offer was to buy Evolve at a super low price. With GCU I purchased Evolve for only $3.99. At that price you cannot go wrong.
