Give. Take. Common sense. Normally works. Ultimately you ain't got nuffin' to complain about unless you agree a price / payment method and pay in a clearly stated time-frame (or turn up in person to pay) only to find some rude fucker has sold it to someone else. It is common courtesy to honour dibs if the buyer is prompt in cmmunicating and paying, but otherwise, sorry, I have a life to get on with, I want some cash in and I want some space. That's my priority, not some dibser who may or may not decide to come back to me 12 or 72 hours later.
I find that most people on here are reasonable, but that the certainty of ebay is often preferable.
Anyone who thinks here is a pain wants to try buying or selling on pinkbike. My favourite ever request on there was someone who (after numerous back and forth messages) wanted a set of my wheels, subject to me travelling 8 miles to meet him a bike shop, have someone check them over, at which point he would make his decision as to whether or not he wanted them. IT DOES NOT WORK LIKE THAT YOU FUCKING TIMEWASTING FUCKING ARSEHOLE. FUCKING TRUST ME, COME FUCKING HERE AND TAKE A FUCKING LOOK, OR FUCK RIGHT FUCKING OFF. YOUR CHOICE.
there, some chamomille tea for you Sir
