I'm in the process... Looking for tips on making the sales process go smoothly. Thinking only cashier's checks or USPS MO. After winning bid contact process? Have my FFL. What is approx USPS charge for shipping "average" handgun? Insurance of course? Geez, so many options. Just need to get 1 or 2 sales done and I'll bet it'll go easier. Just want to have all my T's crossed. Thanks in advance!
