Set up a littlewoods direct account and get 30quid off your first purchase (code ZG 872)and as rock and rose is already one of the products in three for two, you are basically paying 20quid a set!!
Set includes: 50ml EDP, 200ml body lotion and 100ml shower gel.
You could buy any 3 for 2 and take 30 quid of it with the first purchase code ZG 872
(Remember you do have to set up an account with littlewoods direct and the code will not work with credit card purchases, but you can pay off your account using your credit card so just make sure you pay off all the balance as you will get charged something crazy like 40% APR if you dont)
