Has anyone used them, have opinions? Looking at using their service pretty soon, so I was wondering if anyone has used them yet. http://ultracart.com
We used them a long time ago. Not too sure what are the upgrades they have made but our clients could not work with it. It might be more robust now.
Yes, Magento is good with lots of features. We have clients that are using it now. We receive installation request for Magento more than any other free carts.
