Scores in Australia are stupid expensive I agree. I never buy from small music stores anymore! I remember buying Lecuona's Malaguena and it cost me $19.90 JUST FOR ONE BLOODY PIECE. It strange to admit this, but I enjoy printed sheet music 100 times more than books. You can write on them, see more pages at once, you won't be upset if it gets torn up, yes you do have to keep it organised though, every year I have to spend a few hours doing that lol. Nowadays the only sheet music I buy is new music or very very old stuff from second hand shops

St Vinnies, Salvation army, op shops, 2nd hand shops all have wonderful sheet music for like 50c a book (you do have to look out for them though, they are not always there), sometimes really damn good pieces too!
