As my site is not up and running as yet, can someone please tell me what the basic PayPal cart that comes with a BV does with shipping costs. The tutorial shows how you enter in the name, cost and shipping cost for your item. Now I don't want any shipping cost entered into the cart so do I just not fill out that part or do I type in 00 for the shipping cost? When the customer goes to the cart I would like them to see no mention of shipping. So what should I do to ensure this?
