Buyer wants to return goods-refunding post??

Hi All,


I have had a unpleasant transaction over some shoes.Buyer bought with "buy it now".Upon arrival she emails me that shoes do not fit her (all measurements provided in listing) and she wants to return them.I have "returns accepted" in my listing.So do i have to refund the initial post I paid so SHE can try on a pair of shoes?? I hope she does not expect me to also provide return post :0(
