Paypal fee's on combined items

[ICantFindAFreeNickName]

Someone has won 3 items of mine that were all listed separately. I have offered to combine them into one parcel & reduce the P&P charge & sent them one invoice for all 3 items.
Does anyone know how the paypal fee's work. Will I still be charged 20p + 3.4% of fsp for each item or will I be charged 20p + 3.4% of the combined fsp ? ie will i save 40p on Paypal fee's ?

no if you combine them the buyer pays you once and you only pay fees on the one payment, not on all 3 payments

If you combine postage you can send in 1 parcel, so you save paypal and postage costs too
