Last I checked, it's impossible to do a useful "sort by price" for many items. I was looking for...I think it was a 3.5mm audio splitter, and I wanted to find the cheapest one. Searching by relevance mostly returned 3.5mm audio splitters, but dozens and dozens in no particular order. Searching by price returned every single thing in the database with "splitter," "audio," or "3.5mm" in the name or description. Frustrating.
