What's up so cal. I'm Alex and I'm here in Orange County, the city of Irvine. I don't know much for the low carb stores but for supplements I know hands down where you'll get the best prices, at Discount Sports Nutrition in Laguna Hills. There website is dsnutrition.com or # 949-495-3109 to compare prices. I swear I don't work there or make any money by mentioning this or have any affiliation only that from my research they have the lowest prices. One thing I came across while moving along this site was that someone mentioned at in and out you can order a protein burger and they'll wrap the burger between lettuce w/o bread. I thought that was cool. If anyone want's to message me or however it works, feel free.
