I listed a rifle on Gunbroker two weeks ago. I knew I'd get pinched on fees and I always offer free shipping. A guy messaged me and somehow got his phone number to get through. So we texted a bit, then had a good chat on the phone, agreed on a price, he Zelle'd me the money on Sat. and I shipped today. I've had one deal like this ever go south. Somehow you just know if someone is a straight shooter. In fact, I'm shipping my Suhr SL68 tomorrow to a guy who's shipping me his SL67 and some cash and tubes. But we did a similar deal about eight mos ago, text all the time now and we're totally cool with each other. You gotta buy the seller as much as the goods.
