I am pretty interested in some of the items on offer from a certain eBay seller who has been a member since 2001 and specializes in LV (can we name names?), who has about 300 positive feedback (100%) but almost all the recent auctions were private. I thought that was a warning sign that something fishy was going on--what is the deal with private auctions? Do they always indicate a sketchy seller, or are they OK? Please explain!
