I've done a few BIN/BO, but I keep getting lowball offers like $30 on a $120 BIN. The way I figure, if someone wants it badly enough, they'll BIN it, and if not, then a few will be attracted to the low start.
I sold a pair of purple CCAR that started with like a $105 BIN, and a 49.99 start... someone killed the BIN and it ended at like $110. I've also had a few people just BIN outright. <- That's more rare though...
