Where do I find request total in cart,

[alittlepieceofhistory2011]

I  have purchased some items from the same seller and have them in the shopping cart, ready for payment, but I need to contact seller in the U.S. to combine postage.  It does not give me the 'request total payment option' and goes directly to paypal. Where or how do I find the request toal payment option.

Contact the seller and check first, they may not offer combined postage. If they do they will send an invoice for you with the new total.
