Well for starts, now that a bid has been placed you can't just ask for one unless he's willing to replace it with something of equal value, second of all you may wanna watch the tutorial videos. They'll break it down for you
And also, A notice to the seller. Now that the first bid has been placed you can't go saying how much you want for these... That's something you should consider when thinking of your starting bid not afterwords when someone already placed a bid
