Puritan's Pride has good quality products at the best prices I've ever seen.  Once in a while they have the buy 1 get 2 free or buy 2 get 4 free deal.  This is, of course, my favorite.  This is when I really stock up.  I take a multi, B-12, Chromium Picolinate, Fish Oil and Vitamin C on a daily basis and Puritan's Pride is the only place I shop for these items.  If you take vitamins and/or supplements I would highly recommend checking out there website.
