I just wanted to put in my two cents. I know that some of the other reviewers have had a problem with this software, but I have not. ShipRush has improved our accuracy with shipping and our efficiency. It used to take us hours to ship everyday and my guy had some problems keeping organized, not anymore. It has everything we could ask for and I can print packing lists and email my customers right away without having to do a bunch of messing around. It has helped us so much and shipping is so much simpler.
I couldn't live without ShipRush! I can totally recommend this to all shippers.
