My buyer's email address is out of date

Yesterday’s information from eBay on how eBay member to member communications is changing struck a chord with Nick, who trades on eBay as iposters. The following is the history of an unpaid item dispute opened when the buyer failed to pay:

Thank you. I can assure you though that 3 messages were indeed sent. Cheque will be in the post tomorrow.

You’d think it might end there, but no, it continues:

Buyer 13-Nov-08 at 22:19:15 GMT
Please advise as to how much postage and packing is as all I can receive is £3.99 for the poster.

Please click the pay now button on the item. This will take you to the checkout. Select personal cheque as payment method and it will work out the shipping and give you our address.

The news that eBay will begin to ensure users maintain a valid email addresses will solve problems like this at a stroke. The buyer wouldn’t have received the item won email, the invoice, notification that a dispute was opened or indeed any communications at all.

This buyer has over 100 feedback, is aware that the problem is simply that they’re not receiving emails, but still seem incapable of completing the transaction. Enforcing them to update to a working email address would enable them to receive an eBay generated invoice and they could simply pay straight away.
