Bundle.com is a site that uses anonymized spending data from 20 million Visa and Mastercard users, tracked how single men and women spent in 10 categories over the course of six months (Oct. 2010 to March 2011).
To my surprise, men spend more than women on just about everything, including dining out, travel and electronics but they can not compete with us on clothing, shoes and other wear category. At the end we always win! Xo. S.
