So I currently run a fairly large twitter page and I'm really eager to get an online merchandise store up and running to promote to my audience. I'm struggling to decide on what platform or platforms to run my store through... I'm 100% set on using Shopify as my main store platform, but then there are so many different middle-man like platforms to choose from. I've read threads on here saying I should use Amazon Merch, but then they have a fulfillment middle man like teelaunch being used. I've also tried teespring before. Another article I read suggested a shopify store with a fulfillment company called Printful. So I'm confused as to what combination of these platforms will work the best? What's the point of having an Amazon store being ran through a shopify store? Couldn't I just create tee-shirts and products on teespring and link them to my shopify store? Or am I not understanding how the relationship between amazon merch and shopify works?
