I have an Ikea card too.
I received a notification this afternoon from myfico today that my account is closed, and my score dropped 6 points.
Maybe something is happening with Ge Money, because they decreased my JC Penney credit line from $1,800.00 to $1,000.00. I must say, I have not use the card since early 2009. Good thing is that they did not close it out.
It is strange that for you people that went to the store and attempted to use your card that the checkout person didn't tell you they no longer accept Ikea Cards. But as for the Ikea Credit Card, I stopped using my because of the 1.95 maintenance fee they charge per month for every month you carry a balance. When I did use it I paid it off before the statment generated.
