In case you missed it last year, sign-up for a free Atkins Quick Start Kit that includes 3 free Atkins bars, a Carb Counter, and a Quick-Start Guide. This promotion that started last January is still running. You should receive your kit in 10 to 14 days.
I already received mine and it included the following flavors of Atkins bars:
Chocolate Oatmeal Fiber Bar
Sweet & Salty Almond Crunch Bar
Chocolate Caramel Mousse Bar
