Client of mine want me to setup sorting og orders based on payment method in admin.
Basically he wants a way to search orders based on payment method and if for example it is cash on delivery he take the product to local post office and send it...
I mention both sorting and search, either way that solve the problem is fine
any ideas how to do it?
Maybe the easiest/fastest way could be checking at the Marketplace?
Or you can override class Mage_Adminhtml_Block_Sales_Order_Grid to change the _prepareCollection and _prepareColumns methods to add your new columns.
