Used Auctiva for years and it was great. Moved over to Turbo Lister as it was free. When we were told TL as going away, went back to Auctiva and nothing but problems and issues.
Have a number of tickets open and get replies but nothing ever gets fixed. They are putting out some new enhancements, but refuse to fix any problems with the Lister. Importing is a joke as it messes up shipping, and images and you have to open each listing to fix the problems.
Stay as far away from them as possible as no support at all and the forums are absolutely dead.
