This is great coffee - I've ordered from many places, and I often buy from the wholesalers up the road, but there's something about their Espresso Blend that keeps me coming back.
And at $20/kg shipped, that's a really nice price. Expires in 36 hours (end of 31/5/12).
To get the discount, order 2 to 6kg online, then apply the BOGOF coupon.
Edit: Shipping to Sydney is $7.90, Melbourne is $9.90, Perth is $14.90 - ymmv.
Definitely rate their coffee.
Fantastic deal.
