Buyers don't pay PayPal fees, sellers do.
You can go to PayPal as already suggested but you can make an invoice with every single listing number showing. I did that when somebody bought a whole whack of stuff off me a while back.
Request Money -> Send Invoice -> then do it. You'll have to keep adding lines to get all the items in but you can put the listing number, title, & amount for each item.
Personally, I like it that way rather than just say eBay items but that's me.
