Ecommerce does not have to be expensive or complex. Integrating with Paypal, Bitcoin, and major credit merchants can be as easy as selecting a drop down and filling out a basic form.
Shipping automations and automatic price quoting for shipping can also be included in your shopping cart experience. No longer will you need to custom shipping quote on every order that comes in. It's true!
Also manage the multitudes of ecommerce logics you may need:
Custom Sales Discounts
Shipping Discounts and more.
