The random displays of gratitude have pretty much dried up. I wouldn't be holding my breath. The odd ones that have come out this year have been invitation only, so not the old free for all that everyone can access.
The 2664 promotion is often accessed every month by some members here, so it can be used more than once. Apparently you just need to keep trying it (although trying it every day for over a month hasn't seen me get past the expired message, but others have more luck).
