I know this offer was on about 3 months ago! But it's back! I bought 4 boxes of hair dye (2 live colour xxl - about £6 each and 2 colourb4 - £10 each) which should have been £36 but with the deal was £16!!! Amazing price; especially when it's on everything!
Think it should be countrywide; don't see why not. I've visited three Asda's within the northwest and the deal is still live in them all.
Available online too!
