Logitech Z506 5.1 Surround Sound system for $69 from JW Computers
To get the price to $69 use the code JWWB001. You can select pick up in store. Delivery charges to nearby arent bad $10 but might get a bit too expensive if your in QLD or Perth etc.
The price at other stores varies a bit from $149 to $79 with the median being around $90. Although not high end these speakers deliver a pretty solid sound.
The deal is only on on Saturday.
