Since we're on the topic... which of these shopping cart plugins will also handle creating shipping labels? I have a client who is using zen cart for just a couple of products, and would like a new option that can be integrated into WordPress. I don't know which would be her best option, so further recommendations would be great!
Thanks everyone for your recommendations and votes! I ended up
choosing Ecwid - http://www.ecwid.com, which was recommended by
someone on another group. I really like it so far and would recommend
anyone looking for a shopping cart plugin to check it out. ;)
