Nah, the seller point blank refused to honour the sale. They were a business seller so it would appear they just stone-walled it out (based on the four negative buyer comments they received alongside mine...)
Typical fleabay really, they claim it's a binding sales contract but when it suits their profits they'll do whatever it takes to protect their self-interest.
It's rather a pity actually as I had every intention of setting up some of kind of charity auction or raffle. I saw a good charity called Greenhouse wthat perform lots of decent initiatives with city kids, which I thought might be both a worthy recipient as well as a neat parallel given the camping dimension.
Maybe next time.
