£2.35 each on AliExpress, and I usually buy two or more of things like that. Gives me the opportunity to use one in a prototype of whatever I'm making and a spare for a final finished unit (I make it sound like I'm manufacturing things!).

If the components I'm messing with are much more than that price I won't buy multiple.
