Buying feature nickname! Auctioning off the money for it, it's a bit confusing. Here's how it'll work: I'll have a starting buying price, the starting price that I'm willing to pay for the 50 dollar feature is 375k. The person that bids offers a cheaper price than asking. Players will bid down and down until there are no longer any players willing to sell at that price, and you will win! Let the bidding begin: start 375k GO
I may be able to sell you my $50 coupon for $400k, depending on how long you believe it will take for you to get the money.
