So in my first 14 days on Amazon Merch I've made $235.60. For people who use Merch, is this a good amount? Do earnings usually increase a lot the more designs you're allowed to sell and the longer a shirt has been selling? Also, how long does it take you to move up a tier once you have sold the required shirts? It's been 5 days since I've sold 25 shirts but I'm still only allowed to sell 10 designs. Cheers for any answers.
