I just saw this in the list of recommendations whilst browsing on

Customers who wear clothes also shop for:

Clean Underwear from Amazon’s Target Store

It raises two issues. Firstly, do they have a lot of customers that don’t wear clothes. Secondly, are they in the habit of selling dirty underwear? It strikes me as a bit of a niche market. At this point you’re thinking “he’s stupid, it’s a brand called Clean”. I followed the link and it wasn’t. They honestly seem to feel a need to specify that it’s clean underwear.
