Owner of Kiosk, a New York City-based store stocked with souvenirs from her travels (kioskkiosk.com).
On bargaining "I never talk people down on a price. If I feel someone is taking advantage of me, I just don't buy from him or her. In certain places, I always factor in a minor markup; after all we are not locals, and it's OK to pay more since, in these cases, we have more."
