Shipping Option

Hello,

I want the customer to have the option when checking out if they would like to add shipping to the order or not. As some will be for pick up. The only option I’m seeing is that the shipping IS or ISN’T required when I add a new product. I don’t want pick ups to be charged for shipping.
