I love the spice rack very much. It's very attractive in my kitchen. However, there is no manual telling you how to get the free spices, just a small print on the outside of the box. 

I registered for free spices a few days later. Come to find out I needed the code, which is printed on the inside of the box. I dug threw our garbage can -my favorite thing to do- and found it and I am no registered to receive free spice refills for 5 years.
