If you already bought a pack, you can submit one public post. It can be an X post or an Instagram feed post or Reel that shows or talks about your avatars. Mention coolagents.co or tag @CoolAgentsco. The account needs at least 201 followers when the post is reviewed.
One approval adds $19.99 of store credit, once per customer. It is not cash. A three-pack cart can come out to $0 before tax. A smaller cart keeps the leftover credit. A larger cart pays the difference.
