Every month I make an Amazon Merch numbers video sharing my sales numbers and revenue from Amazon Merch. Over the past few months of me taking Merch By Amazon more seriously and being consistant with creating and uploading shirts I've seen a ton of growth on my account tiers and my income. Big surprise right, you put in time and effort and you reap more rewards lol. Anyhow, it was only about 8 or 9 months ago I had a month where I sold one single t-shirt and made $1.96. Fast forward I start putting in more effort, uploading consistantly and month after month I've set new personal bests and sold more shirts and made more money. This past month, December I absolutely crushed my previous personal bests by almost 3x. I sold 313 shirts and made over $1100 before accounting for cancellations. I'm too lazy to do the math but I'm going to say even after cancellations made well over $1,000 probably more like $1050. Amazon Merch is a numbers game. Be consistantly listing shirts. If you find a niche that's working triple down on and and start bombarding Amazon with t-shirts in that niche. Play around with trends and niches and see what works and then go hard. Use big bold designs as they are easier to see in thumbnail shots for buyers shopping on Amazon. Do these things and you will start making more money on merch and you'll continue growing in terms of tiering up and getting more uploads available to you.
