We buy discounted items because discounts tell us which items to buy.
For a given product, there are usually several competing choices, and most people don't have enough time to evaluate whether each one is a good deal for the price it's offered at. So the easiest way to select is to just pick the one that's on sale--or if they're all on sale, pick the one that appears to have the biggest discount relative to the MSRP.
The discount also tells us "you should buy this now, because if you buy it later, the price may go up."
Without this important signal, customers don't really know which one to buy, plus there's no urgency to buy the item now, because it's always that price.
So, while Johnson's approach may have "made sense," and may have worked for Apple products because their market position and product lifecycle makes discounts unnecessary, this strategy really didn't play to consumer psychology, at least in the apparel space.
