Master Card and Discovery policy change
It seems there has a been a fundamental policy change in how to checkout. Recently it seems to affect Master and Discovery only but authorize.net plans to extend this to Amex and Visa as well. This policy claims to punish each mearchant on the internet if not followed by May 1st, 2010 (later it was extended until June 2011)!
It says that each web shop MUST offer several payment options for ONE transaction if the sum on ONE payment module is not sufficient.
Can you please clarify?
