We are getting closer to opening up our zencart store but I am trying to figure out all the shipping stuff. I have been looking at the Endicia site at the premium package but am kind of confused about how to go about setting it up. I know it can be used with zencart but what exactly do I need to download and do I need to do anything special in zencart to enable that option? Anyone who uses zencart and expedia, I'd appreciate any advice/wisdom. Thanks in advance!
