I had a sale.. yes, that's very strange, but that's not the issue..

a clothing item with free postage...

then I get an email asking me to cancel, as when they purchased, and went to pay, they say they were unable to pay , and a message said to contact seller for postage costs.. so she says, she doesnt want it if she has to pay postage..

I looked at the sold item, and under postage & handling, it says, in red, " hazard sign " Posting cost can't be calculated. Please enter a valid postcode.

its from one nsw address to another..

what on earth might be going on..

has anyone else had a similiar issue and know how to fix?

maybe some buyers are seeing that and passing by..

I might log out and see what I can find out

any help will be appreciated.

not sure if it's a one off or a serious problem

thank you
