I just thought I would tell you about this new site for searching for cheap alcohol (in my case BEER!)

Apparently you will be able to search for the cheapest alcohol in your area. The article I read said that the site is linked to all the bottleshops in OZ. Just enter what you want - Victoria Bitter - and then your postcode and search.
It will work for wine and spirits as well. But I'm just going to be looking for the cheapest case of VB :)
