Getting a "your item sold" email from eBay isn't surprising in itself, especially when it's based on a "buy it now" 30 day listing which could happen at any time, BUT....
...it was surprising to see this $50 item had sold through the new Global Shipping program. I didn't even know I was enrolled in that.
When I then tried to send an invoice eBay pops up a message that I can't do that for a global item. OK. That made me look at this carefully to see if it was a scam from this buyer who had ZERO FEEDBACK. Nope, it's a genuine email from eBay and shows up as an item needing payment in my sold listings area.
SO, I went to the help section in eBay and read a few pages about the new global shipping program. I printed it out because there are several multi-step pages in there about how to opt-out of the global shipping, opt in, etc. There is even a section that says if you have exclusions built in to an item for sale that they an be overridden!
Needless to say it will be interesting to see how this plays out. I WAS able to look at the profile for the zero feedback buyer and one slim line shows he is in Australia. I also sent him an email detailing some of what I have said here and asking him to respond. Since all eBay based email is kept by them it's just backup in case something goes wrong.
Meanwhile, AFTER he pays I ship the thing using eBay labels (which I always do anyway) and it goes to Kentucky where it is then taken over by the global shipper. If this thing works right I might stay in the global program...we'll see. I have had bad luck in the past with two items to Canada so I have only sold to the USA for many years now. This might be the change date.
