I like the start, but without shipping options I cant use it professionally. Have had 4 companies interested in it, all turned it down and went another way just for that reason.
The other big problem from my point of view is no support I know of for files in easypopulate format. This is basically a csv with headers formatted for the content. I wanted to do a site today in it, i either write an importer or use another cart, and the client wont pay for me to write it!
I do hope these 2 problems get fixed soon so I can use this for customers. For downloads or simple stores, it is a nice addon!
