Are we talking about any business, or just gun-related ones?
I know a lot of people hate on Cheaper Than Dirt, but in non-panic times, they do have some really good deals. I understand supply and demand, and the pricing that comes with this. I don't hold that against them.
For vehicles, I have bought several from O'Brien Toyota. I can't say enough about good it is to deal with them. They know that when I want to buy, I ain't screwing around, and the only thing that matters is negotiating the price.
For insurance, 3 years ago, I would have said Nationwide, but I can't say that any more. They threw away a customer of over 20 years with their BS.
My old transfer FFL quit the business, so I found a new one, and he's great. Really nice guy, but I won't mention his name here without permission.
Pop Guns used to be awesome, and gave me some really good deals, because they also understood that when I wanted to buy, we had to meet on the price. Don't know what they're like now since the ownership/ name change. My kids loved the Newfoudland that ran around behind the counter.
Beech Grove Firearms has always been awesome to me, but I haven't been there in a couple years. Maybe longer, I'd have to check my receipts.
And F AT&T. I will never do business with them again.
Cheaper the Dirt has a screaming deal in 9mm. 50 round box of S&B fmj for $59.99, makes me want to scream.
