For Prime members only, Amazon offers the Perrier Pink Grapefruit Sparkling Natural Mineral Water 16.9-oz. Bottle 24-Pack for $14.68. Check out via Subscribe & Save to cut it to $13.95 and bag free shipping. That's about a buck under the price you'd expect to pay at your local store, although we saw it for $4 less last November.

Note: Be sure to cancel your subscription after receiving your item to avoid being billed for subsequent shipments.

Update: The price has dropped to $13.48 before discount, $12.81 after.
