I found a gun on gunbroker at about 100 less than normal from a seller that has 1 A+ review. This seems really sketchy to me, especially since the item that the person bought was at the buy now price. I've decided not to buy the gun he's offering, but it raises a question for me. What are some of your experiences? Do's and Dont's, warning signs etc... I like to think that I'm savvy enough to get by ok, but I am also pretty sure that type of confidence is sure to get me screwed at some point. Would love to hear all your thoughts!
