At Puritan's Pride, buy one Puritan's Pride brand vitamins or supplements and receive two more vitamins or supplements for free. (Eligible items are marked with "Buy 1 Get 2 Free" on the individual product pages; you can also buy two and get four free.) Shipping adds $4.95. That's among the best such offers we've seen from Puritan's Pride in recent months, although we saw this deal combined with free shipping in March.
