Who does not love Superdrug. It is the UK’s second largest pharmacy, second only to Boots and offers tough competition to Boots. Currently, they are offering free delivery on a £25 spend (just click the link below) and if you spend £40 or more then you can also get 20% off. The code to use is CHRISTMAS20 but hurry as it is only valid until the 9th December 2013 and Christmas is just round the corner.
