I have a page on my site that uses an order anywhere link to add a product to a shopping cart. I would like to also add a checkbox to this page so that the customer can add additional items at one time.
For instance, the product to be purchased is software. I want to have a checkbox on the page that's labeled 'Add installation for $75'. The installation is set up as a product in SS, so the customer would actually be adding two items to the cart when clicking the button: the software and the installation.
Is this possible?
