Hello, I'm building a site for a client that wants to sell product online. I am searching for an easy and affordable merchant software to help me. I don't have experience building this kind of site so "easy" is key. What have you used and why do you like it? Also I'm not new to the web design field, so, if you know of a better intermediate type of software it would help a great deal. One more thing, I'm working on macs, of course . Thanks in advance.
