Not only am I the Diet Diva, I'm also the Cost-Conscious Diet Diva!
Jewel, which is part of the SuperValu family of stores, has ZonePerfect bars on sale for $1 this week. I found this sale in the Chicago area, but it may also extend to other stores, such as Albertsons, in the SuperValu family.
Whole Foods has Balance Bars on sale for 50 cents each. This is a great price for Balance Bars, so I'd recommend that you stock up. Check the nutrition label on the Balance Bare Bars...they're yummy, but I don't think they're all 40-30-30.
