I I thought that GNC was a good place to go. However I noticed that their prices are ridiculously high. Vitamin Shoppe and are tremendously lower in price compared to GNC. One good thing is that GNC will price match as long as it’s inside of a store. They will not price check on items online. The guy at the store was a little bit rude on my shocked expression when I saw that the price for Isopure drinks were $ 20 more than Vitamin Shoppe. If you ask me $ 20 more is ridiculously high. Another tip is that if you shop at Albertsons next door they have a 30 percent off coupon that prints off on the back of your receipt.
