Basically, next time list it for one price and say whether or not you bought it from a forum member with a link if you can, that should really be the same or less than you bought it for obviously, unless you've made additions as you pointed out which is fair enough, it still might be over priced but thats for people to argue over.
It's not an auction site, check the rules on that one, so if you offer £140 and someone accepts it, its theirs unless they drop out, you decide the price and if some offers more after someone has offered the full price then it's too late.
tbh the next sale you do should be faultless after this experience!
