I order the carmel nut bars, coconut bars, and the peanut butter bars from Nashau Nutrition....and they are to die for yummy (especially the peanut butter...taste just like a Resee's cup)
We use Pure Protein bars sometimes (chocolate kind) and we also get bars from Lindora.com...the carmel nut is the best but I also like the peanut butter crunch...there are a couple others that I like there but can't remember the name.
I just got my order from nashua nutrition today and I bought a box of the chocolate decadence bars (made by proti-thin). They are on par with IP bars and are soooooo good!
