Except they do the same for non-new products which muddles things tremendously.

If I don't see a price I assume it is out or they only have used ones. Certainly occasionally I have seen scalpers when I double checked anyway to see what the price would be if it returned but generally Amazon caught maybe half the scalpers in my experience.

Having a signal that means "you could get it less elsewhere" be the same signal as "I only have scalpers" isn't exactly good for consumers.

Also this implies that Prime shipping is worthless given they exclude it from the calculation...
