As requested by some Spree users, we have launched a new extension for Spree - the most flexible shopping carts powered by Ruby on Rails (that's why you see the rudy on the rail in the pic - TeeHee). To install the AfterShip extension for Spree, it is easy and you can then automatically track all your packages and notify customers at different delivery statuses. Give it a try and we love to hear what you think - good or bad or new ideas.
