Change is hard and I understand your frustration, but it's not as simple as cutting down sizes. To make money you need to manufacture in bulk and it's not just product cost, but packaging, labeling and other related expense. The more product proliferation, the more complications in the supply chain. I once used the McDonalds example for Dr G - remember when McDonalds had a limited menu (burgers, fries, soda, shakes, etc) and the food was cheap and fresh (I worked the counter in 1968)? Now, with so many choices, the process becomes error prone, costly, with cold food the norm.
Optimum had new technology in spray polishes, something no one else had, and we decided to ride that product line. While there are issues with sprayers, the old line had equal frustrations with product separating and becoming difficult to use. As the sales moved into the Hyper products, it was an easy decision to sell out of the pastes and consolidate. By the way, every industry does it - McDonalds only brings out the McRib occasionally and try to find a Plymouth, Pontiac, Mercury, Oldsmobile, etc. Progress...maybe not...but it's life in the Wild West!
