A tier 3 sub is the highest subscription rank that you can buy on Twitch, and costs more than 5 times a tier 1 sub. The benefits of purchasing a tier 3 sub is negligible to none. The most you'll get are a few more emotes that tier 1 subs do not have. Therefore, very few people purchase it, and the ones that do are mainly very loyal fans who want to show their utmost support towards their favorite content creators. Can also be gifted as a very special present to someone.
