Puritan's Pride offers five Puritan's Pride Vitamin D3 5000 IU 100-Softgel Bottles for $9.95 with free shipping. (Add five to see this price in cart.) At $2 per bottle, that's tied with our mention from three weeks ago and $20 under the lowest total price we could find for five bottles elsewhere. (For further comparison, we saw a single bottle for $4 last month.) It purports to help maintain a healthy immune system and bones.
