Mount & Blade Product Key Help? - mount & blade free serial code

Ok, I know you can buy the product key on the website of M & B, and then download the game for free, but currently have only bought one copy of the game and to be sent, but I have a question. is the product key is included with the purchase of the game from the battle in the store or do I buy the product key online paper, which I bought in a store? I would like to clarify just to thank you for answering future ahead.
