A lesson in opportunity cost

I thought I'd go for a saunter to McDonalds today. It's been such a long time since I've eaten one of their Filet O-Fish burgers; at around £2.80, the burger is more of a junk food luxury these days. On the way to the golden arches, I passed a charity store and popped in to look at the little shelf of classics.

Thinking of transactions in terms of second-hand book equivalence almost always results in a trip to the book shop.

I burgerlessly walked home carrying two books.
