If they are GSM wouldnt it be possible its a load of stolen milestones?
I think you hit the nail on the head, stolen milestones.
Yeh right, 500 stolen milestones?
This is a scam I don't know the unit only cost of these things but I would take a guess that they are 350-450 ea judging by the fact that I didn't see anyone selling more than one w/1000+ feedback (indicating it is a company) for less then $450 The ones selling for $350-400 are just indicating that the seller purchased the phone for 200 and renewed the contract.
500 units would be worth ~$162,000 at liquidation pricing meaning that this person would loose ~$112,000 compared to if he had priced these out at a movable price.
Full retail pricing on these would be $280k
I suppose the way an ebay scam would work is something like this. Rack up a usable amount of feedback then quickly sell a very high volume of something product within a small amount of time so that while people are "waiting for the item" no negative feedback is reported. Take money and RUN!
I don't know if paypal has changed their safegaurds but it used to be that if you opened a dispute in paypal about an item all paypal would require from the seller is a tracking number. If the person sent you a fake or different item paypal would tell you that all they do is make sure they sent something and its not their problem if its fraud.
This happened to me 2x once on a Movado watch. Was shipped an empty box and then again with a port, polished, built complete race head they shipped me a stock, used, destroyed head. Paypal said too bad.
Make sure you use a credit card that will eat it if you bid on things like this.
