This option will only be avialable to these customers, not individuals. (All other individuals will buy products paying online.) 2)Add shipping module 3)From main tool bar remove Books menu,change "Help" to "Contact Us",and change the smart deals Flash to a file I will provide. 4)Integrate CCAvenue Merchant account for credit card payments.
