I've never seen them sold in health food stores, I buy mine through the internet. Some will say to buy your own ingredients in bulk and make your own if you want it cheaper. I choose to buy mine once monthly, as an associate, to get it cheaper than retail. You can have them set it up with an auto-delivery where they automatically ship it to you the same time each month and they just bill your creditor debit card..... to me that's better then having to go to a store!
