Merch by Amazon is a t-shirt designing platform. It allows you to get your own designs in front of literally BILLIONS of Amazon shoppers. You simply design, upload, and then get a few bucks every time a shirt sells (you pick your own royalty per shirt. Amazon charges around $12-$15 depending on shirt style and your set price. Anything after that, you get to keep). There’s no shipping or customer service to take care of, Amazon simply prints and ships your designs.
Merch by Amazon is free to join (do it today! – maybe when you get accepted in a year you’ll want to!). The catch here is that you have to wait for approval. The time until approval is completely arbitrary. There are reports of people waiting between 4-13 months to get an invite. Also, sometimes they don’t even send you an email and your account is approved and then terminated for inactivity before you even know what happened. To combat this, just try to log in on the Merch website about once a month. If you can get in and see a dashboard, you’ve been approved. You now have 120 days to upload your first design.
