Pat,
Definitely, make it clearer on your site that those older balls are still in stock.
I've visited your site a few times over the years looking for stuff -- I'm not a pro shop, but a hobby driller who drills for just myself and my wife -- and I saw all this older gear and figured, "there's no way they still have THAT."
I think you need to make it clear that yes, you do have THAT in stock. Now that I know you have older gear in stock, I'll surely check back more often. I like to drill older stuff from time to time when I'm trying to craft a certain look (particularly on dryer lanes).
I should have contacted you to be sure, that's my fault. But if the Web site made it clearer, I bet you'd get more business.
Jess
