I'm giving the promotion a shot considering I'm getting my cards front page exposure currently 25% of the time. If there gets to be too much competition (promotion user base gets too large), then I don't see the value. It will be interesting to see if it drives any sales.
I do find it odd that several "house" accounts are listed amongst the promotion, which essentially waters down the front page exposure rate for actual paying sellers.
COMC Prices Dropped and Auto-Accept set to 20%!
