This usually goes for $129, cheapest I could find elsewhere is Amazon (ships from UK) for $99.69 + Delivery.
15% off last until 11.59 tonight, reverts back to original retail price of $29 after midnight - which is still a bargain! If you get two of these, you get free shipping too.
Likely that this is a price error, but I tried ordering anyways and just received the tax invoice & shipping details for my purchase. Let's hope this doesn't get Ozbargained (fingers crossed!)
