[Help] Buy Now button

I am in need of some assistance with creating a 'Buy Now' button for one of my products. Below is both the image I would like to use and the link to the button. I am just having trouble putting the two together.



<a href="https://sellfy.com/p/EtuC/" id="EtuC" class="sellfy-buy-button">Buy now</a><script type="text/javascript" src="https://sellfy.com/js/api_buttons.js"></script>

put


where it says Buy Now
