Make a mental note of who they are. When the smoke clears never do business with them again. Tell all your friends about them too.
That's my philosophy too.
When my fav gun store on the Front Range closed down I started doing business when I'm over there with another LGS that has in the past year has kept fair prices. The other day I was in there and they had received a shipment of H4350. $49.99
I know the store owner and I told him he was taking a short view that may come back to haunt him.........
