Two years ago, I saw a nice straight grip 16 ga. Lefever G grade at a local shop. The shop owner told me it was a consignment. I thought the price was a bit high, and asked if he'd take an offer.
It took a whole one minute phone call to the owner to get a positive reply to my offer, so I bought it. My savings was more like 20%. If the shop owner gave me some crap about only taking offers to the seller in batches, I would have walked with no regrets.
Your FFL guy saw he lost a sale, and didn't care. So telling him his policy is bad wouldn't change his mind. If you have a monopoly on something, you can get away with being rude or obstinate. There are too many other guns, and gun sellers who would make that phone call.
