And if they can figure out which ones are not coffee makers, why not show the list without coffee filters to start with?

Because I do not trust them? I've seen them get it wrong -- and once you know that "sort by price" may not, in fact, give you the lowest price, it becomes completely useless.

I would not mind if the filtering was optional; but it is not, so this is one more reason to avoid Amazon.
