Similar to this deal - http://www.ozbargain.com.au/node/51912 - at the moment it's $50 off $300.
Text copied from previous deal (with numbers updated):
Just sign up to the IKEA email list and you get a $59 off voucher valid for a spend of $300 and over. I signed up and received the "rent cheque" by email in a couple of minutes. All vouchers are unique and valid for one transaction only. From the T & Cs, looks like you get one voucher sent each month. Validity of voucher is coinccidentally one month as well.
Mod: Fixed link
Looks like you get a 'rent cheque' every month, with a different offer each month.
Now, here's your challenge - try to stack the rent cheque with the eat your discount deal (and post pics of your $250 meal)
