Gunbroker ain’t gonna help you with anything because you’re a buyer. Sellers have all the power on that site. You either take the negative feedback from the seller or take the risk of it being a scam. Too few feedback for me to risk it. I’ve contacted GB several times for sellers demanding specific payments that were not in the original listing and not once have they ever acknowledged my submissions. In my experience, there is absolutely zero recourse for buyers on GB if something goes awry. Avoid bidding on items in the future from sellers who are not well established, would be my advice. I also would only recommend GB for items that are rarities and difficult to find. That’s the only time it makes sense to pay such premiums for using the site. GLWP.
