I bought a bunch of stuff when it was on sale and I had coupons so it was pretty cheap. My overall impression is don't bother!
The wrap kit(southwestern) was fine but I could've done better on my own. The dinner entree and pizza were small and bland. Plus using these products for lunch or dinner, you still need to get yourself a veggie somewhere b/c Kraft isn't giving it to you-certainly not 2 cups worth.
I bought the cookies but heeded the warning about may cause gas(sugar alcohols) and was too nervous to risk it, lol. I did however try the cereal bars(chocolate ones) and found that they were ok in a pinch (but I would only eat 1/2 at a time-still afraid of excess gas
Also like Anna said, SBD doesn't focus on the # of carbs rather the source of the carbs...sugar=BAD carb whole grain=GOOD carb
If you want a good cracker snack, reduced fat Triscuits are good.
