Poor availability
I used this for the first time and paid $18 for two pieces of music. I wanted the Louis Armstrong version of What a wonderful world for piano with guitar chords but it wasn't available in the key I wanted, so I got the Eva Cassidy version, which has the lyrics in the wrong order and doesn't have the nice jazz chords. You would've thought such a well known song would be available. The other order was "It must be love", which didn't have the original chords. Waste of time and money.
