question

I need to be approved for a merch on demand account with Amazon, how in the world do I make that happen? I must be missing something here. I've worked a disgusting amount of hours on designs and marketing. I don't like the other shop avenue I've taken and would like to redirect customers to Amazon instead. Please help, I feel like I've wasted months on something that's just not gonna happen. I'm an artist and just want to be able to put my artwork to good use! Thank you to anyone that responds.
