Amid the buzz about digital media eclipsing the physical world, it must be remembered that all the e-commerce being transacted this holiday season means boots on the ground - the USPS - will be marching to deliver. This of course does not include all of the holiday themed direct mail catalogs that must first get into people's hands in time to fuel the frenzy. Estimates of the increase in Cyber Monday sales alone over 2012 vary from 16% to 19% and may settle out higher. The Postal Service estimates it will deliver 420 million packages this year. They remain true to their pledge to deliver as evidenced by the slog endured by carriers in the Milwaukee, WI area last weekend.
