Atm if you use the code winner you can buy two get two free.
If you use their body butters they have the Shea ones at half price (£6.25). If you add two of them to your basket then it lets you add two other things up to the value of £12 and get those two items free. (I think because the butters were more expensive before they were discounted iyswim).
So potentially you can get £48 worth of stuff for £12.50, though you will have to pay postage, but still a bargain
