Instructions:Using the £2 voucher link below, you can then get £2 off the current Asda selling price of £14.33. Making it £12.33 for a 50cl bottle.
You can also use the voucher at Tesco, Morrisons or other major retailers, however I have found ASDA to be the cheapest. Feel free to update this if you see it cheaper anywhere.
Not as good as the christmas £10 deal some shops had on, but the best deal around at the moment. Hope it helps someone for a gift etc :)
