ETA: Buyer sent a text message promising payment next week. We'll see....
Yes and they have changed policies on this recently so keep an eye on it and stay on top of it or they will not credit you back the selling fees. The same thing just happened to me over there on two very high priced kits. Both buyers ghosted me after willing the bids and it seem it is a new world on gunbroker these days.File a non paying bidder and relist it ASAP. If you don’t relist it they will deny the fees reimbursed without complaining.
