Graze Box! Free code inside!

I finally got a Graze Box! :D
Having heard about this a while ago via Facebook, I have always been curious about just how this whole thing works. Apparently, what happens is that you register with them, and then you will get to rate all the food and every week they will send you a different variety of foods depending on your ratings.
So this way, you will get something different in each box, with the ones you like being sent most regularly and the ones you are happy to try sent  occasionally, the food that has been binned will never be sent.
So the box itself looks like this:

inside it are 4 compartments, with different things being sent:
I had Summer berry flapjack, Heart healthy nuts, Super berry detox and Very Nori-sh sent to me after I rated the stuff on the website. each box looks like this:

they are all nicely packed and looks really appealing! Actually cannot wait to try them out. The best thing is that whenever you decided you no longer want the box sent to you, you can cancel the next delivery, making the whole system really flexible, for example, when you are on holiday you can pause the deliveries for a few weeks, and then continue the whole thing!
Now due to this being the first box I got, I have codes for a free box that I can give out!
The code is: N1QZ51ND
