With Cartel Coin cards, you can get Cartel Coins outside of SWTOR.com and receive an exclusive pet along with it. Starting May 28th 2015, the cards have changed to give out new pets, the Juvenile Rancors, and this guide will tell you all you need to know to get them.
Amazon.com is now selling the 2400 CC SWTOR Cartel coin codes for US customers only. Those who purchase the code will also receive a Umbral Blurrg pet.
Players can purchase the Amazon Cartel Coin card from this link here. Here is the provided image for Umbral Blurrg pet. This pet may not be ingame yet as players that have brought this card have not yet received their pet.
Note: This is for US customers only with a valid US billing address.
