Depends how you define "expense". A good service provided at a fair price, all stakeholders benefit. My CSA share of a farmers produce gives me cheap, quality veggies and gives the farmer consistent cash flow regardless of disease/weather/whatever. We clearly both benefit. Someone else buying UPFs from Walmart because they have literally no other option to affordably feed their family in their neighbourhood... maybe not such a good deal for the consumer.

P.s. Profit is the value in excess of the cost of good sold, not over what the buyer values it as. In a "good" transaction (where the parties are transacting at parity, without monopolistic/exploitative practice) the price is less than the consumer would be willing to pay (the "value" for them) but still enough for the seller to be compensated for the risk and cost they took in buying/making and stocking the product.
