IMHO, it's cheaper to buy it in bulk and cap it yourself. GNC is notorious for marking up already inflated prices from manufacturers. Kilosports.com used to sell ALA for just over 200 beans for a kilo, but I don't think they carry it anymore. I'm sure if you searched on the web, you could find another bulk seller.
My store actually marks up from normal GNCs even....it's a franchise and the boss royally fucks people over...we charge 23.99 or 60 100mg caps...no bs.
