I only shop on the gnc website during a sale, and for Black Friday they had 40% off the entire site so I purchased a box of quest nutrition bars which rarely go on sale. When checking out you have the option of using shoprunner, which I have an account with, so my order came within two business days much like amazon prime. I have never had a problem with my online orders and I know that if I did I can always return it thanks to GNC's great return policy. Overall, the site is easy to navigate, offers the shoprunner service, and has great prices if you have a gold card. GNC is the best place to get supplements and vitamins.
