When I grew large amounts of vegetables to help off set the cost of feeding growing kids it was more important to me to have good food that did not have chemicals sprayed on them and the convenience of going to the garden picking what I wanted instead of getting in the car and driving to the store to pick pick up tomatoes or apples and other fruits that I had in my own garden. Also gardening is fun to me and gives me peace, so if I save a few dollars ok if I don't save a few dollars ok.
