The Restaurant Depot has 24 packs of San Pellegrino Flavored Beverage - Variety Pack (2 flavors) for $12.99 each. Flavors vary by location. In Austin they carry the Limonata/Aranciata this month.
They also have specials on other beverages such as Perrier Sparkling Natural Mineral Water (11.15 oz. bottles, 24 ct.) for $11.39.
I buy the Mexican Cokes there. 24 500 ml bottles $20.99.

Membership is free for business owners. BTW, you do NOT have to own a restaurant to shop there. Pretty much any type of business will do.
I shop there about twice a month and save tons of money. If you have a large family and buy a lot of vegetables you can save a lot.
