Wallis have an extra 10% off all sale goods until midnight tonight when the sale ends. However, if you go through Boots Treats (an offer on for 1 week)you will get 20% off Wallis goods, but it's best to use the 20% off today as they are giving it on sale goods too.
Follow this link and put in "Wallis" in the A to Z of shops.
