I've been part of that program for a couple of years now. I just used $10 of my rewards yesterday to pick up another TBS Hoth Rebel Trooper for about $12.
The one gripe that I have with the rewards system is that I couldn't use those rewards for preorders or online purchases - it was for in store purchases only.
Yeah, that's still the case. Luckily they seem to get new stuff in pretty regularly.
