I certainly don't cover my time rolling baits (and I just do a few for myself). What I do get though, is the freshest bait possible, using ingredients I know are the best I can buy.
For me it's like the difference between, for example, bread in a bag, or freshly baked from the oven. I know what I think smells and tastes better, and what's likely to be eaten first.
This was certainly the case last year when I was catching loads on my own boilies. I don't think I can put a price on that For me it's home rolled all the way.
