Hi Carolyn,
Sorry to hear about your eBay troubles
I think that the bidder can leave you neg feedback, but you would be able to dispute it because he did not read your ad.
I have had similar problems in the past. Not with shipping locations but with shipping in general.
When I have listed in the past I bolded that my method of shipping was "such and such" method. If a buyer didn't like it, then they shouldn't bid.
Only later after the auction is won do they come back and ask me to ship it some other way that I know is a bad...badddd idea. I've gotten into email arguments over this with bidders because they want to save maybe..20 cents lol.
Bottom line though is that if you state something in your ad, then you have the proof to back up your claim and regardless of what they say or do, you are the one in the right.
