I know that merchandise on the shelf is money spent on the shelf, but you've got to have the stuff there where peolpe can see and hold it. No one wants to have wait for you to get a 660 in to compare to to a 460 or whatever.
And not that I'm an interior decorator, but make the place look like a saw shop. I don't like walking into a crappy store that looks like a hardware store with saws tucked in the corner. I know that Stihl will set you up with a nice display....you have to pay for it, but dangit, it looks nice. Even saws displayed in a spar via bore cut, or laying across a milled slap is more presentable than saws sitting on a vanilla shelf like at a pawn shop.
For me, I know what I want when I walk in, so having it there, and having the saw shop look like a saw shop lets me know I'm dealing with someone who takes the saws seriously, and not just selling them to fill up room next to the lawn mowers, generators, and hammers.
