Atkins Advantage at GNC are 3.99, but you get 20% discount if you buy the box, and another 20% discount if you have the gold card - it's worth it. So the bar is only 2.50 there. At Shopper's Drugmart I bought for 2.99.
But watchout, everytime I ate 1 bar, my ketostix went white again, and I called Atkins hotline, and she told me I can only eat one, and only if I replace a meal. I did, and was out of the purple again! So I quit until I lose a lot of weight!
