This is all part of the Ebay's screw the seller policy. They know damn well you can't prove a tracking number, on parcels shipped first class, or priority. Just a customs number that can be tracked as long as the parcel has not left the states. However, in most countries, the buyer can use the customs number and track it themselves in their country. Tracking numbers are only available if you ship registered mail, express mail and if the country your shipping to accepts insurance or signature required, if so,you can use the insurance number as a tracking number or the signature receipt check with your post office on availablity to the country your shipping too. All else fails, you can ship UPS, or FEDEX they do offer tracking numbers but costly. Or you take your chances and gamble. The only country that is a thorn in my butt is shipping to South America were newbie buyers do not realize that it can take up to 14 weeks to get their items, and what was told to me by established customers of mine that live there, what mood customs is in to release the items, or how many peso's can you grease the customs or postal agent's pocket. Example, customs in Brazil has just released a container of mail and packages after 3 months of sitting, which I had parcels on that load, because customs stated that there were too many items coming in from the U.S., pretty suckie uh? When shipping overseas, the best thing is to mention the time span for delivery in your description. Use this for what's it worth.
