This case of 24 Perrier Sparkling Natural Mineral Waters was already on sale for $19.99, but the price for two cases (a total of 48 bottles of sparkling water) drops from $39.98 to $31.46 when you apply the code SPARKLING20 in your cart at Jet.com. Shipping is free on orders over $35, otherwise it adds $5.99. That breaks down to less than $0.66 per 16.9 fl. oz. bottle, which is the best shipped price we can find anywhere for this water. We don't expect these to last long at this price. Note: You can use the same code for 20% off other products from Perrier and San Pellegrino. Sales tax is charged in most states.
