Went to IKEA Southampton today and they were giving away vouchers to swipe at the kiosk to see your surprise. You just have to make a transactions and then you get a swipe card at the check out. I won a kids play tunnel which is worth £10. I think they are doing this everyday till 22nd February. Not sure if this is nationwide. I SM not a regular IKEA shopper but will have to go fairly frequent till 22nd February.
