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.
Please help me sell my remaining 21,699 COMC inventory items - Auto-Accept set to 20%!
