My own experience of 'local producers', is that major supermarkets had them bent over a barrel. Either conform, sell at our low prices at bulk, or get the fk out.
And even before CV-19, some producers decided the stress for producing for SCOTE (for example) , wasn't worth the hassle. Apples weren't the right shape or colour, etc.

Supermarkets used their 'buying power' to cut prices for the consumer (and maximise profits for them), but I think this may be coming back to bite the supermarkets.

They'll only be offered £1.3m with 'add-ons' for a eventual total of £2.1m
