Same buyer, 3 different user names so far

[k*selling*stuff]

I have a buyer who has now just bought his third item from me. All were recent sales, so hopefully everything will be ok. He pays right away, all items with shipping haven't been more than $5.50 each. But each purchase has been with a different user name, and each has 0 feedback. All have been same person and address. Does anyone know if there is some reason for this? Is there some wierd scam or something? Thanks.

Building a feedback history for each user name

If it's a bunch of odd numbers it could be a guest account. Ebay generates random numbers and the customer can't do combined shipping.

I agree with @ersatz_sobriquet  I have gotten guest buyers who have made several purchases in the same day.  I think they must be leaving eBay and then returning and purchasing again which would give them a new guest user name.

Good Luck Selling!
