BOS, same thing here with me.
My positive feedback is Mak +32 here, +2 at the ak forum, +2 at gunsnet, +1 at gunco. The other sites reflect the actual amount of deals I have done on those sites. On this site I have done over 100 deals most of which was my selling items, none of which I have ever had someone make a complaint.
I have even seen where some guys have a WTB ad up when they have bought something from me and I throw in the item (such as a trigger guard for an AK) for free. One time a guy from Prescott, AZ was looking for a Bulgarian AK-74 barrel, I had an extra parts set and I just wanted the plum furniture and I contacted him that I had the barrel and we agreed on the price. I sent him the entire parts set minus furniture and he didn't leave positve feedback for me after I left it for him.
Guys tell you they are going to leave positive feedback but only about 30% do. You have to point the feedback thread out to new members. On some of the sites, if someone leaves a member feedback, the other member gets an IM telling him that feedback was left and has a link so you can leave feedback for the other person.
It's a sellers market here and if I see a guy who doesn't leave positive feedback for me he won't be getting anything I might have that he needs in the future. My choice in selling is to hook up someone I do prior deals with. I've had repeat buyers and people who send more then my asking price but it just rubs me wrong if I hook someone up with free parts (including free shipping on something) and they don't even give you the courtesy of a +1.
