Add a button to product page in shopify based on IP location

I’d like to have a button below the traditional add to cart; “buy on amazon US” and “Buy on Amazon UK” etc,…but only show the button to a customer visiting our webpage from that region. Redirect is to a specific product.

How many monthly users do you have? If is <1000 we can user free API[https://ipstack.com/] to detect user’s location and add required buttons accordinglty.

Also can you provide me with the URL of your sore and let me know where the link will go?
