Also I like the concept. I think anything around improving e-commerce websites especially with variable pricing is smart. One issue is that as you hit $100 it may seem pretty unfair to buy something that someone has bought for $1 previously. Maybe the pricing should be non-linear compared to quantity. As in there are 10 shirts available at $50 and 1 at $1 and it not going all the way to $100. Just a thought, but I guess if in practice you find that the $100 are easy to shift then...
