# TODO get the cart integrated with Stripe
# Steps to convert our Cart into something that can be used with Stripe:
#
# - Sort out the webhook
# - Associate each of our resources with a Product item
# - this should be done in the create resource page
# - or we can do it manually for the time being
# - Check that we can add resources to the cart
# - When the user hits the cart page, each associated product is pulled from the database
# - prices are extracted from the products accordingly
# - use the form from the landingpage.html as the checkout button to call the create-checkout-session
# - Add delete buttons the checkout page, etc
