I've sold an item last night which I had listed as collection only. Stupidly I had the payment method as PayPal rather than cash on collection but as soon as it ended I emailed the buyer though eBay to say cash on collection would be fine and offered some suitable collection times. They then paid via PayPal. I then noticed they live at the other end of the country so messaged them to ask if they are local at the moment and ask when they wanted to collect. But I've heard nothing. They have a low feedback score so I'm wondering if they are new to eBay and don't realise it's a collection only item. Maybe they are waiting for me to post. What should I do if they don't respond to my messages? There is someone I could offer a second chance offer to but I don't want to do that too soon especially as the winning bidder has paid.
