Ikea - sign up for monthly deals
So, I signed up - more from curiosity than anything and within a few minutes had received the first month's offer..
...and the first offer is a voucher to get $15 off when spending over $100 this month (not sure if that is August or September?)
No guarantee of what the future offers may be, but I think it will be a $off with minimum spend.

terms and conditions here: http://www.ikea.com/ms/en_AA/customer_service/terms_conditions/rent.html but they seem fairly standard.
