Have you heard about Bountiful Baskets? They are a GREAT way to get a lot of fruits and veggies for a decent price. Check out their site here for LOTS more information. They are currently in several states and definately have MANY sites in Arizona. There are two in Casa Grande!
You can choose regular or organic (for an added price). Bring a basket, box... whatever with you to take your produce home. You don't get to choose what comes in your basket but there is a good variety and overall I have been happy with the value.
Just thought I'd pass on another great way to save our families $.
