A mention for Amazon search here. Which is a very slow horse and always has been, when even a horse that can walk would greatly benefit their customers.
I can only guess that for some reason Amazon think they make more money by not making search work. Work, generally, like only actually returning things with the search term or, work specifically, like letting you specify hard drive sizes above 6TB.
But I find it hard to believe this shit horse actually drives sales. I always end up looking elsewhere in frustration.
