We want to offer promotion (e.g. $10 off) as long as customer uses a specific payment type (e.g. COD).
I can easily set up the rule for the $10 off in the “Shopping Cart Price Rule” and select “Payment Type” under “Cart Attribute” for the “Condition”. But get error when entering “Promotion Code” on the Cart page. If I remove the “Payment Type” condition then the “Promotion Code” works.
Even though “Payment Type” is available for Shopping Cart Price Rules, is this functionality working?
For payment-type rules it's preferred to not use a coupon code, as the coupon will not be able to be activated unless you've first entered payment details, then returned to the cart to enter the coupon, then return to checkout to complete.
Rather set this up as an automatic pricing rule. If you want this rule to not be able to be combined with other rules, set 'Stop other rules from applying' on the rule, then set it with a lower priority.
I have tried to implement this in default Magento 1.9.2 with the above condition you have explained in your question. I am able to get 10% discount at the checkout if the payment method is "Cash On Delivery".
