I opened a NPB case against a buyer yesterday. They have now paid but made no contact with me and it's not showing on my ebay account. I just had an email from Paypal to say that I'd received payment. Shall I just send the item out and mark the item as payment received? I think it's a bit odd that the buyer hasn't added a note to say why they've been ignoring me for a week but then pays up immediately when ebay get involved.
