Is it possible to clone a Shopify store?

It's possible to clone your Shopify store, however, you should keep in mind that doing so to a store that you don't own is illegal.

That said, if you want to duplicate your Shopify store, simply:

1. Log on to both Shopify stores
2. Ensure that both stores are on the same plan, as well as have the same theme installed
3. Export CSV. files for customers and products
4. Prepare your media for export (URLs are needed as CSV. files only support text)
5. Import CSV. files to your new store through the customer and product pages
6. Reinstall your apps
7. Reconfigure your store settings such as taxes, shipping, checkout, and payments
8. Blog posts can be copied and pasted and store navigation will need to be recreated
