Update: This blog was originally published on March 9, 2017. Since that time, Amazon has indeed entered the package delivery market. This new development makes the information and advice below even more pertinent today than it was when originally published almost a year ago. Make sure you understand what Amazon's move means for the package delivery business as a whole.
If you're a small-package shipper, the prospect of Amazon entering the package delivery market is intriguing. Currently, doing business for you means working with a handful of carriers (typically UPS, FedEx and often the U.S. Postal Service), so your clients have the best possible shipping options.
