That's a very good idea, and nicely worded, Lori, thank you. I think I'll use that.I usually send those bidders an email. Something like "Hi, I see you've bid on my auction and you're new to eBay. I just wanted to see if you had any questions." If you've got a legit buyer, they will usually email back and thank you for contacting them.
Update - I accepted my 0 feedback bidders Best Offer, and she paid immediately! Yes, we all did start out at zero once!^Good advice! Not to hijack the thread, but in my case I have an offer on a handbag from a 0 feedback bidder, same thing as the OP. Do I accept and hope for the best?
