Just got an email from Five Senses Coffee offering a free 250g bag of any house* coffee, just pay shipping ($4.40 for Perth Metro, $7.70 rest of Australia for orders under 2kg).
From the email:
* House Coffee: all blends and single origins. Excludes Limited Release coffees.
Plus if you order before midnight on Friday, 13 December (WST) you are entered into a draw to win a prize package that includes a La Marzocco Mini espresso machine. Most of their house coffees seem to be priced at $15 so it's a good deal for nice coffee.
