Since Virtuemart 2.0.20 there is a new One Page Checkout feature included in the core Virtuemart. We decided to compare the inbuilt One Page Checkout soluton with our own extension. The main difference is that Virtuemart's core solution is NOT a One Page Checkout because it requires the customers to visit another page to enter address and return back. Our solution tries to make the process of the checkout much more simple with a minimum amount of clicks needed, no additional pages need to be displayed and all data, methods and taxes are automatically calculated during the filling of the address.
