The quantities on the site reflect what's included in a daily pack, and prices on the product pages are the price per month! So for example, Vitamin D is $5 per month, and you'll take one pill per day. You'll get a box with 30 daily packs. That means your cost for Vitamin D is $5/month or about $0.16/day.
