My local grocery store carries uflavored Unjury in the health market section.  You might check your grocery store or the health food store.

GNC or Vitamin shoppe

I get mine at Super Supplements.

Don't use unflavored, but I know they do have it because I have seen it there in many brands. They also carry the Jay Robb, which some folks seem to like better than other unflavoreds.

Happy Shopping=)

 One of my local GNC stores sells the Isopure unflavored.  It's $41.99 for three pounds.  I haven't picked up any yet but plan to do so soon.  

Something I just found out about GNC is that not all stores are the same.  There are franchise stores and corporate stores.  I stumbled onto a franchise store yesterday and their prices were cheaper on things like the Isopure Zero Carb protein drinks and they had the unflavored protein in stock that the corporate stores did not.
