Bought a long out-of-print book "Rudiments and Theory of Music" back in January. Our new pup ate it a few weeks later.
Music teacher today referred me to it, so I thought I'd better buy another. Found one 2nd hand on Amazon, and bought it.
Opened a drawer in my desk, looking for something else, and there was another copy of the book. Doh. Must have bought a replacement copy, but I don't remember it. Anno Domini..... Maybe I'd better refer to it more often so that I know where it is.
Have emailed the seller to ask (nicely) for a cancellation.
