I'm Ann, from the team here at Shopify :)
When it comes to dropshipping, there are tonnes of suppliers all over the world you can work with, but finding the right supplier can definitely be tough. I'm afraid there is no list of suppliers we have handy, but there is a guide that might help you track one down!
Check out this guide we have, it goes over all the ins and outs of dropshipping. If you head to chapter 3, it then goes into detail all the different methods you can try to find the right supplier to work with for you and your business.
I hope this helps! If you have any more questions or concerns feel free to reach out to us on this thread :)
Have a great one,
