This is my case:
I bid on digital camera,and won.I promptly proceeded to pay for it,but was refused by Paypal, saying that my item had been cancelled or withdrawn.The "pay now"button had gone,and so was the item listing.Meanwhile I found similar item elsewhere on ebay,and won that time(I also paid for it right then and there).A day or so later,previous item had been "reenlisted",and attached message said that I have to pay it!? Why do sellers pull stunts like that? I don't trust sellers like that,and certainly don't want to do business with them.Ebay already threatened me with suspension of my membership if I don't pay that seller,without any regard for my side of the story! How would you people out there react to a situation like this one? Would you trust a seller that acts in this manner?
