I want to buy a pallet of Dasani water, where can I buy a full pallet of cased Dasani water?

You may want to try Amazon.com or something similar online and take a number of bottles with you. Bottled water, however, is not always the ideal because of the costs, regulation, and health aspects, so if you are interested in something like a sports bottle with a filter in the cap, try www.mosteffectivefilter.com. They are the best I've found for out and about or just around home. Hope that helps.
