Women control 73 percent of U.S. household spending while juggling work, home and family life, and many manage to cram extra hours of activities into the standard 24-hour day, according to The Mall Behind the Spreadsheet, a white paper from AOL Advertising, New York, and OTX, a Culver City, Calif., research company. Multitasking is the name of the game - especially while at their places of business - as 40 percent of women shop online during work hours.

Overall, women tend to shop between 15 and 30 minutes a day while at work. Moms, though, tend to shop for longer periods of time at work, with 37 percent citing it is because they have more downtime at work than they do at home. Women ages 18-34 conduct about half of their online shopping during work hours. Fifty-three percent say they shop online at work out of convenience/to save time; 40 percent to pass time; 38 percent because they need it now; 20 percent have no time at home; and 35 have the most downtime at work.

And what are these ladies buying on the company clock? Clothing is the No. 1 purchase choice for women online, with books and movies in second place. Following these categories, women enjoy spending nearly equal amounts on electronics, shoes and travel.

Need is the main driver for women's online purchases. However, boredom and a compelling call-to-action can inspire younger women to shop. Sixty percent of women respond to an e-mail offer, making it the most influential driver of purchase, and three-fourths of women subscribe to e-mail alerts.

Women shop online more at work on Fridays than on any other day of the week, and about half of all women do their shopping between 11 a.m. and 2 p.m, as lunch and other break times provide the best time to shop. Fifty-four percent shop during lunch; 41 percent while multitasking; 46 percent during breaks and downtime; and 25 percent right after seeing a "deal."
