I've ordered somthing on amazon and got 2 free coupons for graze.com. One for you and one for your friend (notice: you can just use 1 Code for yourselfe).
First Code: YOU9H7D
Second Code: PAL9H7D
I cant use them because i live in germany and graze is just for UK residents...
Have fun with your boxes, it would be nice if you write under this thread when you pick up a code.
