Need a solution to manage shipping for your ecommerce site? Look no further than www.shipstation.com
I did a lot of research in this area and we have been using shipstation for over a year. It is awesome and affordable. Saves us many hours in shipping related labor.
UPDATE: Not long after writing this post, the company was purchased by Stamps.com. Shipstation is now the most popular shipping solution for ecommerce. Just a few months later Stamps.com (ticker STMP) bought the #2 player ShipWorks. The stock then tripled in price over about the next year. The final piece to the ecommerce shipping management monopoly was purchased by Stamps.com last summer when the company purchased ShippingEasy.com
