Currently, I use quick2cart on one of my site. I am pleasantly surprised by this software. Quick2cart is really very simple to use, easy to understand. I think it is a very powerful software.
However, I find a shame that languages are not already pre-installed. The translation has to be reviewed to simplify handling.
However, I am very satisfied with the support. Because I think this is the strength of this software is also the quality of support. I'm waiting for the sequel, but I remain confident.
