Thumb Score: +8 I got a free $1 Amazon MP3 albums credit with purchase of the Free Android App Of the Day "Helidroid 3 PRO : 3D RC Copter". (Not sure if is for everyone or if YMMV) Them paying me to "buy" something free, is slick in my mind. Note: I didn't even download the game, so can't speak to it's value, only it's cost.
