Let's just turn the B/S forum into a Newschoolers version of eBay!!
just kidding, kids on here aren't mature enough to enter into binding contracts.
If you want to buy items set at a price, go to a store.
If you want to bid on items in an auction, go to eBay.
For all things in the middle, (and ski related), go to Newschoolers.
Kids back out of supposed "solid offers" daily, and people retract items they put up for sale because they decided they want to keep them. Both sellers and buyers commit these trivial yet selfish/asshole-ish moves. You just have to remember that while dealing with b/s/t on here.
Now, I personally, wouldn't have a problem making b/s/t into a legit eBay format, binding contract, bidding auction, but I don't think most kids could handle it.
As for set prices, YA THE FUCK RIGHT hahahaha. What happens when you post a price way too high? or too low? The point of used/sometimes rare gear is that you don't know how much someone else would pay for it, so you give a price range and see what you can get.
