By default, PrestaShop includes the values 'new/used/reconditioned' to associate to your products when it comes to the 'condition' field.
You have the possibility to add more options in your PrestaShop store, and then add these new values in Store Commander to increase productivity.
Here is how to modify the 'condition' database field to add these options in Store Commander.
/modules/storecommander/XXXXX/SC_TOOLS/settings/settings.php
global $cat_product_data_fields_condition;
$cat_product_data_fields_condition = array('new'=>'Nouveau','used'=>'Occasion','refurbished'=>'Refurbished');
