Everyday I check this site to see what bargains I can find. It is run by an online Bike/Snow company in NZ. But they have warehouses in Australia, on Gold Coast and Melbourne. The sales last for 24 hrs and sometimes have some awesome deals, but you need to know what you are looking at as there RRP can sometimes be way too high.
Just thought I would share.
