Under U is having a 5% off VAT, I believe in the UK. The rate has been cut by 2.5% and they care cutting it by another 2.5%. So you can save a little extra money this holiday season.
They have also released their online catalogue. You can go over and mark what you want Santa to bring you and hopefully find it under the tree on Christmas.
Lastly, they are having a 20% off Christmas undies. So when you go look up what you want in the catalogue, you can find many of the styles on sale!
