Please give your package more than three days to arrive before you start asking me where it is. I love selling international for the most part and typically there are no problems but every once in a while I get a buyer who thinks there item is being teleported.
I always answer in a professional way and advise them of any tracking etc. but it makes me a bit nuts when someone emails nearly every day about a package mailed first class international just last week.
Ok rant over. For those who still do not sell internationally this does not happen often and I would say 20-30% of my items go international. I guess it's just as likely to happen with a domestic customer but this one is international and just can't get there soon enough!
