I'm new to ebay, and I'm very international-postage savvy, I don't live near a Post Office, I have no car and can rarely afford the bus so I only usually get to the Post Office twice a week. Therefore I put on my item's pages that I aim to dispatch within 5 working days, and I set up a postage restriction list to show that I only post to the UK.
I've lost count of how many emails I have had to respond to from bidders asking me how much it would cost for me to post the item to Lithuania/Italy/Australia/Guam/Mars/etc; or from buyers saying they won the item 2 days ago and it hasn't arrived yet........
And one from a buyer who had purchased a pair of USED toddler shoes from me and was emailing to complain that the soles showed that the shoes had been worn.......
Grrrrrr rant over!
