My point wasnt about helping out the SELLER, it was about helping out the BUYER or potential buyers. There is no way to tell who is going to stumble onto a for sale thread and therefore the only way to inform everyone of any kind of better deal would be to do so inside of the thread. PMing the seller might make them aware they are selling their item for too high, but that doesnt stop them from doing so and also doesnt stop someone from buying that item.
And silversurfer my point is I dont care if YOUR happy or not. You are the one selling your hammock for too much. I'm looking out for a buyer who snags your hammock only to realize he could get it on amazon cheaper. - the for sale section isnt designed so you can make money, its designed so you can pass on old items at REASONABLE prices- what is reasonable I suppose is up to the buyer.
I do agree it shouldnt be used to link to other individuals selling it cheaper, so if billybob posted in your thread he is selling it cheaper I think that is rude. but if its on amazon, or rei, or some other mainstream website I think its in the best interest of the buyer.
