Is there any tools like Oberlo?

I want to import products from Amazon to the Shopify store. Are there any tools for that? Maybe free one?

There are many tools for that purpose, but not free.

I have used Dropified in the past, but I see a some apps that may work for you in the Shopify app store:

https://apps.shopify.com/browse/finding-and-adding-products
https://apps.shopify.com/search?q=amazon+import

From that list, I might test Spreadr first and then some of the other "Free plan available" apps.

I hope that's a step in the right direction.
