I sold an expensive rain jacket last month on eBay. The buyer did not request insurance or tracking of any type, and to keep costs low, I shipped it parcel post. Well, they are telling me they still haven't received the package and that they are going to the p.o. today to check on it (I suspect they are in a rural area). What do I do??? I've never had this happen in all the time I've bought and sold on eBay!
