It would depend on what was on the site and what I was looking for.
Like if I was on your site looking for XLR cables and I got to a page that listed them all.. and say that I could list them in order according to price, I'd probably scroll down as far as I had to in order to find what I needed.
But if it was just random items and I was looking to see what you had, I'd probably not scroll very far at all.
