Integrating Bitcoin Pricetag On Product View And Quick View

I have been persuaded to accept payments in bitcoin for products and services. In order to show what a particular product or service presents in value expressed in BTC we need to implement an example of a piece of code.

I found a page with examples:

The url is build up from a sample url like this one:¤cy=&color=

The price tags for the products, where can I find them and on what line number can I find the specific tag ?
