I just bought some more low-carb protein bars (my favorite), Power Crunch at Vitacost.com.  All flavors!

They are already cheaper by the box, at under $15,  but you get more off up until midnight tonight (11/26) with the promo code of SAVEBIG.  I just saved about $5 a box.  If you buy anything over $49, the shipping is free.

They also have low-carb baking products and gluten-free too.
