Has anyone used Shyp? I started but I can't quite get a bead on it. I punched in a sale I made to a MA address and it actually wasn't a better deal than using my usual method. But then again, maybe there was a step I didn't finish. Have other people used the service and found it a good fit? Is there a trick to it?

I'm just looking for peer reviews. I was going to look up their forums, too, if they have them.
