+1. The checkout is different every site: eg, not all store sites go to payment method (some B2B) or about a code to discount is diferent. Also, not all sites have a checkout method -a ticket/support system is not necessary checkout or payments- About checkout method we developed sale basket (1) module to generate a lines about product, quantity and price. "Checkout method", convert those lines to sale + sale lines. Same as Nereid module, I think checkout is a new module, not included in "Tryton Flask".
