Puritan's Pride offers its Puritan's Pride Double Strength Glucosamine, Chondroitin & MSM Joint Soother 240-Count Bottle 3-Pack for $49.98 with free shipping. (Select the 3-pack to get this price.) That's $16.66 per bottle and the lowest total price we could find for this quantity by a buck, although most stores charge closer to $20 per bottle. (We saw it for $13 less in September.) It purports to promote healthy cartilage to encourage joint comfort.
