GunBroker review: Shipping insurance is secretly third-party

I’ve used GunBroker for many years to buy and sell firearms. On April 16, 2022, I sold a firearm to a buyer in Arkansas and shipped it to their FFL by USPS after purchasing the mailing label and insurance directly from GunBroker. The firearm was lost/stolen by USPS. After several inquiries to GunBroker about the insurance claim process, they finally admitted that the insurance purchased was from a third party, not USPS. They have absolutely refused to provide me with any timeframe for the insurance claim to be paid. I’m currently out more than $1,400 due to GunBroker’s misrepresentation. I will never use GunBroker’s shipping system again after this terrible experience.
