eBay and Craigslist finds

I thought this when I saw these (this?).. It's like when a guy is selling "road bikes" and there is one bike in the picture..

You'd be stupid not to ask.

Clement Silk Tubular Tyre

Me:
Is this auction for a single tub or a pair of tubs?
Ta,
Michael.

Seller:
Please read text it says tyre

Me:
Do please excuse my stupid question and cretinous behaviour, as when I attempt to read any auction text I come out in a nasty rash and thus I rely on pictures. I hope you can now see how the misunderstanding occurred.
Cordially,
Michael
