This was not an easy decision to make however, I have come to this conclusion:
If you want a serious E-Commerce Shopping Cart Do NOT bother with VirtueMart. You will spend MUCH too MUCH time simply working the bugs out of it BEFORE you'll be able to start actually using it.
I have spent countless hours performing "hacks", "tweaks" you name it... just to get this cart to work right. The final straw hit when I decided to update my version to the newest version. I have run into so MANY problems simply trying to do this that I have decided to find something else. I'm an online seller... Not a computer programmer and this has become way too much of a struggle to keep this cart going.
Integrates easily with Joomla! Has nice presentation capabilities.
Too many bugs that are too complicated to fix for the average computer user. No real support for this software.
I honestly gave this Cart more time, effort and attention than it's worth. If you want a practical, functional E-Commerce application I strongly suggest that you look for something else.
