Ikea coupons?

My husband has just given me a challenge. He said that he read online that Ikea has coupons- you just have to find them. I have been googling for a half hour and can't find any Ikea coupons for furniture. I did find one for a plate of meatballs! Does anyone know if Ikea coupons exist and/or where I can find them? Thanks!

The only Ikea coupon I can think of is the $20 WUS $75 from the Christmas Tree promo. You would have had to get your tree there. I would LOVE to find some more Ikea coupons!
