Close. Boxmart - any chain - has a corporate buyer, he deals with distributors or makers that can fill an order for the chain. That means the Corporate Sales Rep has appointments scheduled, has a track record, and can demonstrate the profit potential of turning over a gun on the rack over and over.
Small time gun vendors aren't visiting to do that. They don't even own a $800 suit. They can't get past the answering machine, don't play golf with the buyer, and usually would blow all the profit on the sale just on the airline tickets.
Boxmart only buys from big players - when the Remington Rep comes by, it's all about how they are spending advertising dollars to help Boxmart sell sell sell. He's got inventory in stock and shipping. He's got multiple Brands and can sell ammo, too.
He's one stop shopping, just like who he's selling too, and that's not going to happen with small importers who can't even promise to have the same exact model in six months. Constantly swapping data and printing out a new shelf tag for every non-standard AK that gets imported - dozens and dozens - is just a major headache for merchandising. You've got to come up with another SKU if anything changes on it - it's not the exact same interchangeable product.
Ak's aren't worth the hassle at Corporate, if a store manager wants to tweak his inventory, more power to him. He's happy enough most of the time to just go with the typical Fudd inventory, it sells, and micromanaging one item in a low profit department isn't worth the effort.
He's in electronics milking that Cash Cow for everything it's worth.
