You're welcome. With the Merch by Amazon account, you only have to design, and check for trade mark and or copyright. Know how to use Gimp, or Photoshop. They provide the blank merchandise, taxes, and customer service. You get royalties and just need to pay your quarterly income tax. It takes some time to be accepted, then get through the lower tiers that are allotted to new designers. I will send you the link to sign up if you like.

Thank you.

I can see I misunderstood a bit... This looks cool, and I find it interesting, but I already have a complete, stand-alone product that I want to sell, so I'm looking here for possibly signing up:

Thanks again, my friend, for your feedback! :D

Oh yes, you should do that to! I know of a person that has a game they sell though that, he also does Merch by Amazon. He mentioned it on one of his videos. I will try to find it/him. Perhaps you can get some tips from him.

I found him! This is the video I was talking about.
