If you use Xmasbright you get both of the things put into your basket. You only need one code
Thats happened to me before and they have always honoured it in the past. If its not included ring them and they are very helpful
Can only use one code unfortunately
I ordered the diffuser and a skin set and it let me put xmas4 code in for 2 free gift sets worth £9 each my original order was only for £23 I will have to see if this is fulfilled!
