Amazon offers the Fit & Fresh Jaxx FitPak in Red for $38.48. Clip the 15% off coupon on the product page to cut that to $32.71. Plus, Prime members bag free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $8.08.) That's the lowest total price we could find by $8. It includes a shaker cup, four 2-cup containers, and two 1-cup containers and features five compartments.

Note: It's available in several other colors for a buck more with the same coupon.
