the seller is now not registered on Ebay. They emailed me to say there'd beena cock up with their account and that the item had been sent. As it's coming from Hong Kong, it takes 7-14 days according to their listing. I was prepared to give them the benefit of the doubt.
Now, it's been 7 days and it's not here - would you wait the extra 7 days and then start a PayPal dispute or start it now? It's only £20.
