Query: I wish they'd start packaging them separately again!

This product works fine; the problem is the way they market it. You used to be able to buy the wheels and the fluid separately. However, this package is like bundling a pack of 10 hot dogs with 8 rolls, and forcing you to buy them together, always. At least before you could buy an extra wheel or two before if you had fluid leftover; now I've accumulated tons of fluid that's just going to go to waste, because I can't buy the wheels separately any longer. A way to waste money buy putting it into the manufacturer's product for no good reason. C'mon DI; let us buy the accessories separately again!!!
