Superdrug are currently offering 10% off selected gift sets and an extra 20% off for members. Combined with an already lower than average starting price of £16 (the same set is £22 in John Lewis and Asos), this comes out at £12.67. Think there is a glitch with the website as the maths doesn't seem to add up (unless anyone can explain?) but still a saving of almost £10!
Says 7ml on the listing but 9ml on the image so I'm guessing this is an error too.
