I had an auction that ended yesterday and the winning bidder came in at the last few seconds. He (yes a man) has had 11 negatives and 1 neutral in the last 6 months but his feedback is private so I can't see the comments or if he was buyer or seller. This seems like he has a pattern of doining something... just am not sure what. What also made me nervous is he's participated in 172 auctions in the last month and over 850 auctions in the last 6 months (based on the feedback I can see). I did an advanced search to see if he is usually a seller or buyer. It seems he never lists auctions - only buys. I looked at the auctions and this guy buys only handbags (bidded on 268 just this month). Most are Dooneys and Coach. This buyers seems odd to me and I feel a bit unfomfortable since I can't see what issues others have had with this buyer. Also, payment will be through Paypal, buyer is in the US, and I ship USPS Priority Mail with insurance and delivery confirmation. Since I'm uneasy I'm gong to demand a PayPal confirmed address. Any advice on what may be going on here and what I can do as a seller to protect myself?
