Where Can I Buy Any Whey Unflavored in Charlotte ????

Is there any where in Charlotte that I can Buy Any Whey Unflavored ??? How much is it ??? I went to GNC and got a container of Isopure Vanilla because they didn't have any unflavored. Even with 20% off it was $44.00. It's really good though. I need something unflavored to put in other things when I get to start "real food" on Tuesday. Rhonda
