I made a purchase from a power seller yesterday...it wasn't terribly expensive, but that's not so much the point... Basically, I got an e-mail from the seller saying "oops" the he already sold the item!!! I asked for a refund...which came...but it didn't totally calm my frustration. If you have an item for sale it should legitimately be for sale. A "power seller" should know better then to list an item for sale and then turn around and sell it off ebay during the auction period. So basically I went to leave negative feedback, because frankly this was a negative experience--he earned each and every ounce of my frustration. But ebay won't let me--they said I have to wait "7 days" from winning...but that doesn't take into account that the item will never come, 7 day or a million days. I think this is such a bogus rule. Thank you for letting me vent.
