I really don't get on well with Amazon (uk). Finding products is hard. I mean there are things in life that you research, then there are things that aren't really worth researching. Examples: I wanted an Exercise Ball once, Or a waterproof bluetooth speaker.
These types of search yield generic cruft, and despite all the options, none of them seem to have any meaningful impact in the search.
The only other notable thing winding me up is ebay "not collection only".
