Jawbone Jambox for $50 (with purchase of two bottles of vodka) from BWS, Dan Murphy's, Woolworths
You can do this though for a total of $125 which is great value for the Jambox alone as a competitive price online for this bluetooth speaker is around the $177 mark. JBHifi, for reference, have it listed on their site for $229.
Now you can get a killer price on some killer speakers with two bottles of vodka to celebrate afterwards with while probably saving yourself around $42 at the same time.
