Protein Powder/Meal Replacements for Women?

I'm currently using Isagenix shakes as a meal replacement for lunch or after a workout. I love the taste, and have seen some great results. I have been using it for about a month and 1/2 now, the only downfall for me is the price. I can't afford to keep paying to have this powder shipped to me. I'm looking for something similar that I can simply go pick up at GNC, etc. I'm 4' 9" trying to lose about 10 more lbs and tone up. I know a lot of powders have extreme amounts of protein or are loaded with sugars. Does anyone have any suggestions for me? I'm so lost! Thanks :)
