Politely, shut the fuck up. It is so old.
Your harassing, douching, and cluttering of threads over a 50 dollar quarrel for a pair of bindings or two year old pants is lame.
When you have no intention of buying the product, don't say anything. Just leave the thread. When you want to buy the product, PM the seller, work out a new price on the side with them, or talk about moving the price there. If it works, the buyer will go back to their OWN thread, and update his or her price.
Telling people to drop a price by whatever amount of money, for the sake of lowering the price on their thread is stupid. Telling (usually a friend on the site) "hey man just a heads up these are selling for ___ on MORE THAN one site" is no big deal.
Nobody cares you got 916's from the way cooler guys on TGR for 150, that doesn't mean all 916's are now worth 150, and everything else price-bumps down too...no, it means you got a nice deal, and now you get the ski them and shut the fuck up.
Most of the time, if a price is just too damn high, the seller knows it anyways. Keep fair pricing in your head when you're making your sale and you'll be fine! Just poke around other places for a FEEL on how much you want to sell for.
Stop wasting posts and cluttering threads with your petty price problems.
Moral of the story: Sell at fair prices, PM your deals on the side, and stop policing prices, namely the ones you have no intention of buying.
P.S posting shop prices or your sick pro-form deal price is totally fucking lame.
