I wonder if there is actually proof out there that marking an item up makes it actually sell. These sellers must be using that strategy, I would like to know what they are basing that on. What sales are they looking at? I do not see how this can work. Sometimes I think about getting an expensive BIN (never happened yet), but when I see them mark it up after while, my personal pride will not let me make the purchase.
I could see a strategy in marking something up, up, up then after awhile bringing it back down to the original price, then someone that was watching can come back and jump on that price before it goes away again. But these guys do not lower it back down they just raise it and leave it there, with no accepting offers option.
