If you submit a review of your bank at mozo.com.au, they will send you a $50 Cellarmasters voucher toward a wine(only) purchase totalling a minimum of $120, ie, a $120 order would cost only $70. Might be useful for some with Christmas coming up.
They usually send the voucher via email a couple of days after you submit your review.
They also have a financial Q&A forum where the top question or reply each week receives a $50 Coles Myer gift card. I've never received a scrap of spam from them.
I've just received a promotional email (from sms pup) stating that mozo is also currently a draw for bank reviews submitted - first prize an iphone4s or one of 3 100 gift cards.
