cheapest way you’ve found to get fresh vegetables?

living in a very low budget household with myself and my disabled mother, we both have a lot of health problems and food restrictions. for a few years my main way of buying vegetables has been aldi and grocery stores having clearance when i get lucky, are farmers markets worth trying? or is there a certain day of the week that would be better for grocery clearance? i’m not near a grocery outlet, but i’m near a lot of local farms i’ve considered contacting them and seeing if i could get produce discards or something discounted. i go to food pantries as well but i still have a hard time making it through the month, just wondering any insight to cut corners.
