Jill's pawn shop is a store in Windemere. She has been forced to sell much of what she owns due to the taxes being raised for the ducks, so they don't actually sell anything. Even after the ducks are gone, Jill's Pawnshop still doesn't sell anything.
She does, however, buy longswords, nuts, claw swords and slayer claws (an item which doesn't exist in the game).
