Hi Jeep whisperer
I switched to CubeCart. Fairly easy to figure out but like all of the "free" carts lack of documentation is a bit of a problem.
We have put our entire catalog into an MS Access 2007 database and generate CSVs from there.
Once in the MS Access 2007 database we are able to generate CSvs for Amazon upload, CubeCat upload, and hopefully we will figure out how to upload to eBay.
The MS Access 2007 database makes it easy to update prices, descriptions etc
I may take a look at Prestashop in the future
