Joules have this gift set priced @ £10 each and on 3 for 2 so 3 would normally cost £20 , however if you add 4 which will total £30 and use code BOOTS14 you get another £10 off and there is also free delivery at the moment. There are other 3 for 2's but not many, so have a play around and see what the best deal you can come up with is. Total spend must be £40 before the 3 for 2 for the extra £10 off kicks in. The best deals are for the sets that are £10. Hope that all makes sense?
