Instructions:I am a member of the boots.com heathclub and got a direct email informing me of this. This des not appear to be a unique code but one for everyone to use. Only thing is you might have to be a healthclub member (but it's free so if not join up).
To obtain 50% off you will need to enter the following media code DHMD85.
This code will enable you to buy as many of the products below as you wish at 1/2 price. However, this cannot be used in conjunction with any other offer.
All of the products within the 1/2 price offer will be available on Boots.com shortly.
Unfortunately, only one media code can be used per transaction.
