Hi Jerry, The question should be, what am I really going to get when I make such a purchase? Perhaps the seller is conducting arbitrage (Drop shipping). This is when someone sells an item he does not have at a premium and then buys it from another source at a discount for delivery. Not everyone is internet savvy and all it takes is a few clicks per week or month and the seller is making $$.
I guess knowing your seller (or source) is the best approach to avoid disappointments.
