I bought two identical items which were posted by the seller on the 11th. They should have arrived by the 14th Nov. So far no sign so thought I would send the Seller an email. Found Seller and hit the Contact tab, wrote email and pressed submit.
And, curses, it appears I have opened a case in the Resolution Centre of which there was no warning. So, as I understand it, if I do have problems getting my goods, they have effectively stopped me opening a case with Paypal.
It used to be easy to email a seller ages ago, seems things have changed and not for the better.
