I know where you can buy vitamins at wholesale, but it's not at GNC. It is from The Wellness Company and I know for a fact that it is a lot cheaper and better. I actually saw a demo on these vitamins. There was vitamins from GNC and vitamins from The Wellness Company; there was 2 small glasses of water and this guy dropped both pills in the water and the vitamin from the Wellness Company started breaking up and it dissolved in the water and the vitamins from GNC was still whole. If you prefer to go that route and then let me know.
unless you become a franchisee of GNC, you can't. Each franchisee has a exclusive license, for which he or she pays, to the territory where their store is located.
GNC is, I believe, looking for more franchisees. Try their website for details of how to contact them about this.
