To date, we have not offered ecommerce (shopping cart/checkout) capabilities on our Squarespace site. We have used product pages to showcase our product lines, but potential customers submit a form that we use to prepare a specific quote. We are adding a new product line that will be offered with a shopping cart/checkout feature. Can we enable this on a page-specific basis (i.e., for this new product page only), or, once we turn on the site's shopping cart capability, will this enable it for all of our product pages? Our alternative would be to create a separate site focused on this new product line. Thanks!
