PrestaPricing : module de gestion, création et mise à jour en masse de vos produits Prestashop

I tried storemanager, and got lot of bugs, particularly when trying to import categories and had difficulties to get help. My webmaster mentionned prestapricing as a good alternative and was amazed by what it offers for this price.
But more important is the quality of Sitolog support : I had a question during the installation and ask a question on their tchat. Two minutes later they called me back and completed the installation for free. I even got a 10 min personnal 1st hand demo.
Higly recommended.
