If you compare it to the same product code somewhere else, perhaps. Your parent is stating they perceive the quality at Whole Foods to be substantially better, and worth the price premium. Perhaps they lack alternative reliable sources of high-quality organic produce you might have access to?
That's about the size of it. When you factor in that we've had to discard as much as half of the produce we purchased from other sellers due to it already being spoiled, the actual value for the price at Whole Foods is higher.
