Been waiting for one of these sales for a while - for anyone that still uses physical media. Got an email about this on Friday night - 20% off CDs and vinyl at JB Hi-Fi.
Just in time to pick up that new Taylor Swift album too (released yesterday). The new 21 Savage album is at a great price ($10.39) if that is more your thing.
I think the sale is only running this weekend (11-12 November).
cheers
