Buying and selling advice on oople

[Tayter]

Dear All

I have listed 2 x cars and a bag of spares on this forum and have been inundated with offer to buy. I will always answer the pm's in order I receive them and have answered them quickly and given paypal details out for payment. but still no payments have been received and new offers are coming in still.

What is the buying selling etiquette on this forum, wait for payment and tell others they are sold or sell to the ones who pay the quickest on paypal ?

My gut instinct is to wait for the first offer to pay(and potentially loose a sale) but am I being to stupid and money is king ???

Your thoughts please
