Went to Bill Goodmans gun show in Nashville this weekend looking for a Glock 30sf. I brought along my XDM 45 to sell privately at the gun show in case I found the 30sf at a price I was willing to pay. So I come across a G30sf at Ken's booth, price on the box was $590 but the sticker on the gun said $550. I was comfortable paying $550, so I asked the gentleman at the booth if he would take $550, he looked and said yes, I asked again to make sure, again he said yes. So I found someone to buy my XDM, sold it and went back to Ken's booth to purchase the G30sf, again asking if $550 was the price, yes he said. So I do the paperwork & background, the lady said the gun is $590, I told her about what the guy said, she went and spoke with him and came back saying no the gun is $590. I told her I would not have sold my gun if I could not purchase the G30sf for $550, they would not budge, so I went to another dealer who had the same gun for $10 more and gave them my business.
