I've been doing the App Trailer thing also, building up Amazon Gift cards $1 at a time. Figure I'll save up until the next crystal sale, then cash them in. I work a desk job, so I just keep it running at my desk all day and just keep tapping "watch again" over and over and over.

Good luck with TapJoy. I know I've been really grateful for it, since, like you, my hubby and I swore to never spend real money on this game, and, thanks to TapJoy, we haven't.
