Well I signed up for Bplay alerts and for Xmas they sent out a free $10 gift card to a lot of their subscribers and the day after Xmas they had a 30% off sale...
I bought about 4 games for 5 bucks...
Nintaii, Crash Bandicoot Nitro Racing, Mahjong Solitare, and Chuzzle...all great games Nintaii being my personal favorite!
No free games as of yet, but this was a great deal IMO
heres a link for the marble trap game (10 bucks though)
