OK, i have it figured out. You have to actually download the GOG galaxy and install the game per the directions given by Shareware on sale as below:
Once you have done that, download and install GWENT: The Witcher Card Game on your computer (it is free). YOU MUST BE LOGGED INTO YOUR GOG ACCOUNT WHEN YOU DO THIS. You will get the message you are downloading GoG Galaxy GWENT The Witcher Card Game installer. The filename is GOG_Galaxy_Gwent.exe. Once this completes, install. It will ask you to log in to your GoG account via this client, once you do you you will receive an email that says:
Yay! there are new free items in your library.
One or more new items have just been added to your account at no charge. If you have any questions, contact our support team with your Order ID.
Gwent Welcome Bonus Free
Order total: $ 0.00
THEN, go to the page to subscribe to the newsletter given by the Sharewareonsale instructions, Click to claim your bonus and it will guide you through the process of claiming the game. IT WILL SHOW 0.00 to pay if you have followed all of the steps correctly.
Just FYI, I did try this several times WITHOUT downloading the GoG Galaxy client and installing the required GWENT card game and I kept getting the 1.49 price. Once I followed the latest Sharewareonsale instructions (which I have expounded upon above) it worked perfectly. You will get the message that the game is in your library and the following email:
Yay! there are new free items in your library.
