Amazon offers the Doctor's Best Vitamin D3 5000 IU Soft-Gels 360-Count Bottle for $6.07. Order via Subscribe & Save to drop it to $5.77 and bag free shipping. That's $2 under last June's mention and the lowest total price we've seen. (It's also $5 below what you'd pay in-store locally for this quantity.)

Be sure to cancel Subscribe & Save once your order ships to avoid being billed for subsequent shipments.
