I ordered a used paperback book on music theory from Ergode Books. They offered the specific edition I wanted at a competitive price. Most of the other vendors I looked at only offered an older edition lacking the added content for which I was buying this book. The ordering process was as easy as expected, the book arrived on time and it appeared in almost perfect condition. There was a slight crease in the cover, which was perfectly acceptable at the price I paid. I will check out Ergode Books again next time I'm shopping for a book. (BTW, I have no relation to Ergode Books other than being a customer and I was not compensated for this review.)
