I buy the "Carb Solutions" high protein bar, they are $1.79 at Walmart and they are way better than atkins bars, the capaccino crunch is to die for!!! but I can only eat half at a time and with lots of water.
I havent tried any shakes yet, like has been said, they are expensive and who knows what they taste like!!

If you want to try a low carb bar try these ones, they come in alot of flavours as well..

happy searching!!
