Why wait until products are in stock to promote them? Steve Hall, founder and president of Dallas's Driversselect, peddles the used cars on his website from the moment he purchases them at auction instead of waiting till they're delivered. That cuts the time cars sit in his lots from 44 to 36 days, saving $14,400 a month on interest, insurance, and storage. Sales at the company which he says is like "a Zappos for used cars" are on pace to reach $91 million in 2011.
