The last JB HiFi catalogue I saw had only one page for music and that was only for $9.99 discount CDs.
The new JB HiFi @ Forest Hill shopping centre has music shoved as far into the back corner as possible.
It seems that mythical point where CDs (beyond heavily discounted top 10 and compilations) go away completely is quite near.
At the very least, most CDs will only be available to order online, not in stores.
