Amazon offers the Babyganics Mineral-Based SPF 50 Baby Sunscreen Lotion 2-oz. Tube 4-Pack for $7.01. Check out via Subscribe & Save to cut that to $6.66 and bag free shipping. That's $5 under our mention from last July and the lowest total price we've seen for the quantity. (It's the best deal today by $6. For further comparison, we saw two 6-oz. bottles for $7 in January.) This non-allergenic sunscreen is water-resistant for up to 80 minutes and features UVA and UVB protection.

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