"Whole Paycheck" for Whole Foods?

Kate of Accidental Hedonist's post on the familiar debate over prices at Whole Foods, If the Name "Whole Paycheck" fits..., has already sparked quite a discussion, but I wanted to point out her evidence for a belief I've long held: when you shop for fresh basics rather than luxury items, the cost difference of going to Whole Foods is marginal. For most of what I buy (seasonal and preferably local, organic/natural vegetables and fruits), Whole Foods' prices are actually lower than those of other stores that sell the same quality produce (which isn't Safeway). For me, the difference in quality, in what's stocked, and in the shopping experience itself at Whole Foods and many of the smaller, independent groceries is worth a lot more than a few pennies per item.
