For some reason in Australia ebay does not have the function (or they don't allow it) to send out emails to all customers in one hit. I contacted support via the live chat and they said it was not possible. No help whatsoever..... I did get an email from them though.

I recall reading a post some time ago about logging into a different country ebay site which did allow it, if anyone can help it would be great.

We are in fear now  of receiving low DSR for postage times because we are located in a town that was almost washed away. Thanks ebay, you are so much help.
