I was looking for something else on eBay when a bit of serendipity brought me to this listing.  It amused me greatly that the seller is called sweatysockjock --- and that's he located in Southend-on-Sea, where I believe Coutts does its credit card processing.

When I looked there were no bids --- and Mr. Jock was saying they "can be yours in just a few days."  Only 99p to start the ball rolling.

I actually thought about selling our Coutts leather cheque book covers on eBay (we seem to have lots of them, most never used).   But then I thought, "Nah, now you have gone too far."  Perhaps not.
