Definitely bring food, especially if you prefer to eat Organic!<br /><br />Quartzite, AZ (3,000 year round residents) prices will be pretty high.<br /><br />Blythe, CA (20,000 people) about 30 minutes away, due west, will be pretty good.<br /><br />Yuma, AZ (190,000 people) about an hour or 1.5 hours away, due south, will have whatever you are looking for.<br /><br />Phoenix, AZ (1.5 million people) is about 2hrs away due east from Quartzite, and will have everything.<br /><br />Definitely check out a map, Quartzite is on the AZ and California border due west from Phoenix on I-10 (which will be on every map of AZ for sure).<br /><br />so like blars said, quartzite will have the basic requirements and a high price, Blythe will have a fairly good selection of things at an ok price, and Yuma and Phoenix will have everything you want.
