At work, we use the box above from OfficeWorks. We put the CD/DVD in double-sided sleeve so each box hold like a hundred or more disc. For home use, $18.00 for a plastic tub seem bit pricey. Has anyone seen the same box elsewhere cheaper, preferably in Melbourne.

Another alternative I found is from IKEA. Slightly smaller and not water proof but definitely cheaper. Unfortunately, they are out of stock (indefintely) at the Richmond store.
I already have CD wallets but they are a pain to keep things in order. To insert a new disc, you have to move many disc.
