Total Import PRO allows you to easily upload your product information into your Prestashop store. This module is a must for any prestashop store, it is the result of months of experience in product import with CSV and XML Import PRO,  it is well written, ensuring maximum compatibility with other modules/extensions. Save yourself hours with this module and make inventory management a breeze.

New Improvements:

I have made some improvements to the extension as well to make it better and to make life easy.
1) Category Mapping added to put feed products directly into store categories.
2) when using multiple feeds, you might have faced a problem having products that have been removed from the feed but not removed or still shows on the store,this has been fixed.
3) you can enable settings to delete feed level products while having multiple feeds and with preserving manually added products also.
