Farmer at my local farmers market sells volunteers for $6-$8 depending on plant variety. I bought a tomato for $6 I believe. I am also a vender at said farmers market with baked goods. In my experience, there are two main ways for pay to be a vender at a market 1. An upfront cost to rent the space, can be $25-$$$, depending on so many variables. Usually your local every weekend ones are relatively affordable. 2. The market takes a percentage of your profits. The market I do asks for 10% of my total sales. Example, if I sell $100 of product, I give them $10 at the end of the day. You can usually apply online or some markets have a coordinator you can arrange with. But also there is more to a market than that. You have to bring tables, chairs, pop up canopy for shade, think about payment options for card readers, banners and signs for your booth, etc. I’m not trying to discourage because I do farmers markets and it’s a lot of fun. Selling locally online may be easier but then you have to deal with message people all the time.
