Place Walmart order from checkout

Place the order on an open Walmart.com checkout and get its order number. It places the checkout open in the current session as it stands (address, payment method, items), so run it in the same session after Check out Walmart cart stopped on the review page. Returns the order number, the order total Walmart confirmed and the confirmation page URL. This spends money. Walmart can still cancel a placed order afterwards (for example for unusual account activity); its order page then says so and nothing is charged. Walmart sometimes refuses automated checkout steps with its "Robot or human?" check; the run then fails saying so (nothing is ordered when it refuses the order request), and it usually clears after a pause.
