Not sure if this belongs here but my riding mate wanted a full face helmet, he saw a Troy Lee downhill lid, 'new, boxed, unused' on marketplace in his size. $150 less than retail. He organised a visit to the sellers house. He said the guy selling it opens the door and gives him the helmet box to look at, then gives some story about ordering the wrong size and can't return it.
My mate asks if he can open it and try it on. Guy selling it says 'no, it's brand new, not used, if you try it and don't buy it I have to change the advert and drop the price'. My mate says he just wants to see if it fits but the seller won't let him open the box without handing over the $250 first.
He told him to shove it up his arse and left, said it was a great way to spend a Sunday evening doing a 2 hour round trip through suburbia.. Also though it was weird how a little South Asian guy was selling a XL helmet.
