If you are buying a show, walked the WHOLE show then figure out who you want to buy from. I have seen 20% differences in prices between aisles.
I've done this on numerous occasions without any issues, but within reason. I try not to meet people at night and/or in extremely remote locations; but I have met several sellers in parking lots and was able to complete the transaction with ease.
Those are exactly my experiences also, describes my personal experience with majormadmax to the letter.
I know I am posting this a little late, but I have always found that when I wanted to buy from a gun show, that it is always best to go on Sunday, and preferably after about 2pm. Most dealers would much more like to make a sale with a little less profit, than have to bring that gun back to the shop. Also, I have always got better trade-in values when waiting until Sunday afternoon.
Not a fan of late Sunday either, some vendors wrap up early and head home before the show ends. Feel like majormadmax, if it has been looked at by two days worth of people and no one got it, there might be a reason............
