You've identified a really good supply source there, in fact any clearance type structures like this can be a gold mine because they purchase their stock from liquidation in the vast majority of cases.

In Aus, places like this are Crazy Clarks and the Warehouse. I'm sure there are many more, so feel free to drop a name if you know of any in your area guys.
