It is possible to buy an IKEA gift card at an IKEA store. As of July 2015, it is not possible to purchase gift cards online or by phone. Once you have a gift card, you can redeem it online or at an IKEA location.
To find a local IKEA store, go to ikea.com and select your location by nation. Then scroll down to the drop-down menu under Choose Your Store to select a location by state. Gift cards are available in amounts ranging from $5 to $500 and do not expire. Use them to purchase any IKEA merchandise, including home decor and food.
