You can decide if the block contains a purchasable product. This option determines the visibility of the "add to shopping cart" button, price and VAT for the product.
The product code has the function to identify the product within the orders, it won't be visible to users.
You can choose if the object of the e-commerce block requires shipping, for example if you're selling a service, you can disable this option.
The "shipping cost" is per unit.
For other information on shipping costs, visit Shipping costs
The description field will be visible to users from within the shopping cart.
If the object requires different options, it's better to insert in the body of the block a form
with the extra data (eg colour, size, notes...). The choice made by the user will be added to the order information.
Extra information will be introduced in the order, if needed.
