Re: "REQUEST TOTAL FROM SELLER" WHEN DOING THIS A RED FLAG COMES UP STATING ... THIS SELLER DOES NOT OFFER COMBINED DISCOUNTS
I've run into that several times. If you go to your purchases page and make the request for a total from there instead of the PayPal payment page, you don't get that message and can contact the seller with a combined shipping request.

Just another eBay bit of stupidity...
