I've had major problems getting VVS slips from any Canadian online retailers. I don't understand why either. I did order this from Amazon.ca though. Once I receive it I can post the outcome.
I received Horns from Amazon.ca yesterday and it actually came with the slip. Not only that I ordered two other VVS titles along with it and they both came with slips. Pretty surprising. I have never been able to get VVS slips from the before.
