What do I need for an e commerce site?
I am setting up an oscommerce site to sell products. Should I buy an oscommerce template from Template Monster.com or pay 0 a month on Network Solutions? Does Template Monster have shopping cart software, SSL encryption for secure checkout, and credit card authorization software?
