You may want to try eBay as well.

I recently got a full box ( 15 bars ) of the Atkin's Advantage Bars in Chocolate Raspberry for around $ 15.00 with shipping....retail is around $ 27.50 or more at my local GNC store.

I also got 3 bottles of the Sugar Free/Carb Free Raspberry syrup for $ 12.00 with shipping...retail is around $ 5.95 or more per bottle.

I've seen many, many Atkins and other low-carb products available there.

Happy LC'ing.
