Asda George have an online exclusive event with 20% Off All Women's Clothing and Footwear, and the offer even includes Sale items, so you can pick up some massive savings.
Although the offer is advertised as on all clothing it does exclude lingerie and nightwear. Although it doesn't specifically say either way accessories are included, as I tested it on the handbag in the picture and the discount came off. There is no code to enter, the 20 % extra discount is automatically applied at the checkout.
This women's clothing event is just for 2 days, and expires at 9am on Friday 21st August, so that gives you a bit if time to have a look at what bargains you can pick up. Whether this is to compete against the current 25% off at Tu at Sainsbury's I don't know, but I hope they do a children's clothing one soon as well!
You can use the free click and collect from store service, or home delivery costs from £2.95.
