I recently sold an item to someone on eBay with zero feedback. Now that person paid immediately using Paypal/Buy it Now but it seems that their eBay account is registered to one name while their Paypal account is registered to another. Both addresses are the same, just different names (it's a library in Chicago). After googling both names, it seems they both work at the same place. Anyways, I e-mailed the buyer earlier this week to say that I would have to ship to the confirmed Paypal address to protect myself as a seller but I still haven't heard anything from them. Should I be worried or should I just ship out the item since it has been paid for? I guess I just feel like something is off.
