I know this topic has been raised before, but things change, and the results I've found all seem to give directions that don't apply to PayPal's current layout. So I'll go ahead and ask again.
People who order books from my store need to know if the shipping costs can be combined when ordering multiple copies. This is reasonable, since I use Flat Rate boxes and envelopes, and I don't want to charge an extra five bucks per book when I'm shipping them all in a single package. How can I make it so that there's a single shipping charge for multiple products in the same order?
