I have experimented with the "Add to Cart" button and it seems to be almost useless, unless I'm not understanding the correct way to use it!
First, the properties box has no provisions for shipping costs.
Second, when you click on the button; it takes you to PayPal shopping cart, BUT the only choice for the customer is to either change qty.; remove item; or go to checkout!
How about "Continue" shopping?? Shouldn't that be a choice?
I would probably upgrade to actually sell online, but was wondering why the "Add to Cart" button in BV didn't have a provision for shipping costs and Continue shopping feature?
