the savings to be made are are on
labour
premises.
electricity gas water etc.
packaging
shipping and taxes.
if it comes in at even £6 a kilo for ingredients and you get it right.
you will probably have the best bait money can buy.
Would be interesting if it was possible to work out actual savings between home rolling and commercial using similar ingredients minus trade discounts.
that said,
We all know a piece of corn can be better than ANY boilie if it’s in the right spot lol
