Sometimes, when someone wants the voodoo they are selling, and they have put it up on the market, I think that an optional "cancel sale" should be in order, perhaps it would be prudent to place a time minimum on said cancel, say, a day must pass before you can cancel. Or, if it gets bid on, you can no longer cancel the sale.

i agree

I also agree.

Such would encourage protection of sensitive voodoo. Something that is already forbidden to do.

No I disagree with you Jack, it would encourage people to bid on a cards rather than wait on it till time was about to expire, if you had to sell the card at first to get some funds to keep going and playing, but someone gave you these funds and you no longer needed them, then provided there were no bids and it had been a day since you posted it up you could cancel the sale, again encouraging others to bid on cards or else lose out on the possibility of getting them, I have been playing for several months, and the one thing I see most is that people wait till the last second most of time, the name of the game is to get the most credits for the seller and for the bidder to get it at the lowest price, but we mainly see just the one side in favor of the bidder and no incentives for people to bid until the last few minutes before it goes off the board.
