done, althoguh the words are slightly different

The ad lists 2 wheels, as in plural, there is a picture of 2 wheels, and the description states that it's for a pair of wheels.

but thanks for the heads up on what to write, not that i would have missed it, but his email said:

I have made a genuine cock up listing these wheels, in the quantity box when I put the advert together I put 2 instead of 1 so you and another guy have won the wheels. I don't want any more for them then you and he have bid but you both can't have them so I will email him and see if he is prepared to let them go.

Sorry for all this, I can't believe i've done this and caused this aggro.
