Leaving without buying

Your storefront holds two addresses, each for one way out of Groupon's checkout:

• Redirect URL: the shopper paid. Groupon sends them there with grouponOrderUuid, to the handler above.
• Continue shopping URL: the shopper left without buying, through your logo or Continue shopping on the checkout page that shows your logo. Groupon sends them there as it is, with nothing added: point it at a page that expects no order, such as your catalog. Without it, they go to the site of your redirect URL, or to groupon.com when you have none.

Set both on your storefront's page; GET /partner_storefront/me answers them as redirectUrl and continueShoppingUrl.
