This is my first post and wasn't sure if it was a voucher or a deal, its both depending on whether you prefer the IKEA restaurant or the store.
I was in IKEA Warrington today (no idea if nationwide or not) the offer is whatever money you spend in the IKEA restaurant between 8th Nov and 4th December, entitles you to get a discount off your store spend for the same amount between 6th and 24th December.
Probably not a deal if you live miles away or dislike the food, but if like me you live within 5 miles of an IKEA it works out well.
Basically anything you spend on food in the cafe you get the same amount back at the checkout in store (but not on the same day, so the distance thing plays a part).
So if you want something from IKEA, why not go and splurge massively in the cafe, they sell things that could easily be taken home like sweets and drinks. I eat in the cafe every so often so now I've got £12 to spend on christmas decorations next month.
It's also not really noted anywhere, couldn't see it on the website or signage in store. It was pointed out to me by the cashier and is on the receipt.
THey also also a delicous cinnamon whirl and a hot drink for 50p, this is 35p cheaper than a drink on its own!
