While Trader Joe's produce often isn't a great deal, I'm addicted to their organic baby spinach ($1.99 for a 6oz bag) as well as their organic mixed greens.
Do any other local retailers or big box stores beat those prices? I haven't found one, though bags by weight can be deceiving, so I might have missed something.
Where do you buy your greens? (Okay, my underlying question is: should I join Costco for the greens, assuming I consume a bag or two a day?)
