If your AJAX cart uses a different template than the cart template then you'll need to find the file that holds the AJAX cart code. Start by searching for a file similar to one of the following:
cart-drawer
ajax-cart
mini-cart
1. Adding the button to the cart-drawer file
Open this file and search for Submit. Add the snippet code below the checkout button:
<a href="/apps/request-quote?page=request" class="btn">Request A Quote</a>
2. Adding the button to the ajax-cart
Open this file and search for Submit. Add the snippet code below the checkout button:
<a href="/apps/request-quote?page=request" class="btn">Request A Quote</a>
3. Adding the button to the mini-cart
Open this file and search for Submit. Add the snippet code below the checkout button:
<a href="/apps/request-quote?page=request" class="btn">Request A Quote</a>
