Fantastic range of music, especially if you're into more independent and obscure stuff. Also sells concert tickets (to smaller bands of course). not as cheap as JB Hi-Fi, but at least you know that the people that work here actually know their stuff.
Approximate cost: $25
These guys know and love their music. Focuses on more independent and non mainstream artists. Huge amount of local(Melbourne based) and Australian bands, plus an equally huge array of every cool and interesting band you can possibly think of from anywhere in the Western world. Being a music loving mum with a pram, I have to warn you theres hardly enough space for breezy browsing. On a trivial note, this is a great place to go if you want to perve on spunky fey indie boys and girls! The service is fine. The vibe in there can make you feel like checking there is no spinach in your teeth, cos god forbid you do anything uncool in there. Oh it is also a great place to buy tickets for selected up coming gigs, and sometimes shows at bigger venues. Final word, JB Hifi may be cheaper but Polyester has stuff that you would not find there.
Approximate cost: $30
This is the best place to buy CD's and records as the people there know and love their music with a passion. In this day age of downloads it's important to support music retailers like Polyester records.
