I agree!Farmers' market produce should NOT sell for less than what is at a soopermarket!
I have been attending the local market for several years now and have actually built a client base. People come specifically to buy from me. Interesting how that happens.
I don't dicker. Put a price on it and if they want it they can pay the price. Generally, my prices are about the same or a little higher than supermarket prices. I can't sell by the pound as I don't have a certified scale, required legally, but I can weigh things like squash at home and decide from the weight what price I will put on it. They go to the market priced "Each", never by the pound.
I joined the local market as a venue for my honey, and the produce makes enough weekly to fill the gas tank. Veggies have never made enough to warrant my time spent at market, let alone time and effort to grow it.. If it were just for veggies, I would not attend the market. I'd rather give it to the food bank.
I grow a big garden for myself and family, however it always produces much more than we need so there is excess.
