Walmart isnt number 1 in supplements. It is the number 1 retail store though, because it sells things for cheap, and believe it or not most people in America are hicks.
Maybe you should be more specifice when stating what they are the largest in the business in of.
You stated:
Buy a 1 month tub of protein from GNC for 55-60 or buy a week supply for 15ish, a lot more economic if u ask me, maybe that's one of the reasons why Walmart is the largest in the buisness...
Big difference in protein. Whey protein concentrates with soy fillers are cheap everywhere (Costco, Wal-mart, Fred Meyer, Vitamin Shoppe). Whey protein Isolate is the protein that most people are after and you will not find these in many places besides a GNC/Vitamin Shoppe/Nutrition Store
