I bought a crusher and precrushed a second batch of grapes before pressing the grapes. I've got to be honest. The results weren't much different to just putting the grapes in the crusher whole. This is going to be really expensive if I'm only getting about 3 litres per 8 kilos of grapes. How do grape juice companies produce such cheap grape juice? Are they getting (much) better prices for bulk purchases of grapes?

Freezing them and defrosting might give you a better yield, as the juice-containing cells rupture when frozen.
I've only used grapes once, but got 1.9l of juice from 2.4kg of grapes.
