Okay, it is a bit ominous that this fourm seems to be rather dead but I am enjoying oscommerece and I trust amazon so here goes. I am using the checkout by amazon for v2.2 on a oscommerece v2.3.3 installation. It seems to work but I would like some confirmation from other users.
The main error that I saw was that the new login.php and shopping_cart.php have references that point back to a file includes/column_left.php. This is the old style of layout for osc, in v2.3.3 column_left and column_right.php are defined in the administration side of the site instead of being seprate files. Simply adding a blank file /catalog/includes/column_left.php will allow the module to work. This is an ugly hack, as it strips the formatting in login.php and shopping_cart.php but it works. Seems like there should be a better way so I am going to keep looking. Thanks
