I just started using this service, but I have had friends use it in the past. It is definitely not the most "organic" company in Seattle, and they get a lot of stuff from out of state, but if you are like me (an amateur cook), its definitely a great place to start. You can get it weekly or bi-monthly, and you can pick what kind of mix you want (ie more fruit than veggies, herbs, or whatever you want). Also, if there is something you always want while in season, you can make it a recurring item. I have been happy with it so far, but would love to hear what others have to say.
