I'll have to side with Dann on this one.
The moderators would rather the seller leave the asking price showing in the thread. This way, when doing a search, a member, regardless if it's a Gold or Basic menber, can have some price history on the knifes being sold on the forums.
Yes, as Gig One stated, you could ask the seller the selling price, but to me, that is rude, and really none of your business. Besides, if the posted price was left alone, there wouldn't be a need to pester the seller in the first place. Read 'hassle factor' here.
Also, as Dann stated, us moderators DO NOT EDIT POSTS unless it is absolutely necessary, then we post a note saying why we did the edit. I wish other members here would do the same, but that isn't a hard rule for the members in general.
Bottom line here, folks, is that this is a community of knife nuts, and we all need to show some common courtesy towards one another, and leaving the asking price in a thread isn't going to harm anyone, and it will help provide some history on the models being sold here.
