Mac Pro and Mac Book Pro buyers please beware- probable EBAY SCAM ALERT- Potential Ebay buyers of Mac Pro computers and Mac Book Pro items should be careful on listings from buyers with very low or zero feedback and recent registrations. (I know, sounds obvious, but some people have been taking the bait.) There is one seller who has been listing very expensive Mac items in new or nearly new condition- often with suspiciously low buy-it-now prices- and free shipping under multiple user names. After receiving funds, this seller sends empty boxes with tracking numbers to wrong addresses, which buys him time to sucker other buyers. This scammer has received negative feedback from multiple buyers on his previous user name, and is now jumping around using other newly registered user names. Check for very recent registrations (at least for now, some are being registered in Pennsylvania) for the seller on the item you may be bidding on, and consider yourself warned. Ebay is investigating, but until this individual is stopped, this person can reregister under new user names to "clear" his negative feedback from his profile, throw Ebay fraud alert authorities off his trail and steal more money. PLEASE- Fellow Mac users and buyers beware!
