Dont bid on the ebay auctions for lots of xbox 360 they are all fradulent and all ask for wester union payments. there are on ebay auctions all the time. Rarely you will se one that accepts paypal but they are also fradulent. Who will sell 30 xbox 360 for 3000? it doesnt make sense because they could make way more money than that. i know this because i tried to negociate with them but they all want wester union and in one auction i bid, but ebay send me an email that said that the auction was a fradulent and that it was under investigation.
There is no such thing as a free lunch. If something looks too good to be true, then it probably is. Look at what the cost per unit is of a bulk deal like that and if it is unfeasibly low, then steer well clear!
