John,
I think most people are afraid of offending a dealer if they make an offer. The U.S. is different from other countries in that bartering seems to be only allowed in certain segments of the market, expamples would be buying cars, homes, etc.
And there's alot of tire kickers out there too...I'm guilty of that myself...when I first started buying doubleguns, I kicked alot of tires.
I've made dealers offers..what I would consider very fair offers and 95% of the time..I get treated like shrek. Chased out of the shop with pitch fork and torches.
A dealer had a gun for sale and the price was $3650....I offered $3000 and I pay the shipping, his counter was $3600 and I still pay the shipping and that was his final offer...in the beginning, he too asked me to make an offer.......
