Change Function of Add to Basket button

Hi = is there a code injection or workaround in the 'ready' template - I need to change the functionality of the 'Add TO cart' button - so instead of adding product to cart - it will direct a potential client to the contact page.

If you're not going to use the Squarespace cart and checkout process I would recommend using normal pages or blog posts as product pages.

They are far more flexible for presenting the features and benefits of a product and you can use normal buttons to link to the enquiry page. 

What if I wish to have a store that uses the Squarespace payments basket/checkout system but I only want to sell products / allow products to be purchased for, eg one hour a week. Can I stop purchases, or maybe redirect the Basket's 'checkout' button to a holding page?
