Dawn,
Good luck to your ebay business and dealing with this buyer.
The other members gave you great advice and since I have only shopped on eBay once so far I have nothing to offer in that regard except for best wishes.
This is off topic but kind of related to eBay and internet shopping in general. I guess I don't understand why sellers send along free gift. IMHO it seems to send a subtle message that the item on its own is not good enough or that the buyer overpaid and so the seller can afford to send along more jewelry or gemstone freebies.
Something informational like DVD, calendar, if sent only once, would not give the same message.
Cheers,
Pernula
