I do about 90% of my business on Gunbroker. There’s no other auction site with as large of a reach to potential customers. Selling fees have steadily increased. I hardly sell any new guns because Buds among others are selling at wholesale prices. Drop shipping items that they don’t purchase until that have your money. They have good feedback but you will see comments like took forever to get after I paid right after winning the auction, or won the item but no that say they don’t have it.
If Iist something, I have it. I have had a few problems but mostly due to slow or ruff handling by USPS.
