Never been to that particular store so I can't speak to it itself ... but if you are local or go often to a privately owned store like that ... I've found a few conversations and return trips can make it so that you can usually cut a good deal off any "sticker" price on guns or knives.
But each store is different. And as someone mentioned a lot of smaller gun/knife stores get many window shoppers. And many customers don't like pushy sales help so they do usually ask once and then wait on the customer to initiate further assistance if wanted.
