MonsterCommerce is better than many products, but there's tremendous room for improvement. Oh, did I mention that their WYSIWYG editor doesn't work with Internet Explorer 7.0? It probably never will, either, from what I gather from the discussions their forums.

I know what I said in the "Good Points" section, but as I type all our issues out, I realize I wouldn't recommend this to anyone. If NS wants MC to continue, they're going to have to give it a ground-up overhaul.
