Unauthorized Resellers

Unauthorized resellers:
  • May offer product that is much less “fresh” than that offered by authorized resellers
  • May offer product with damaged packaging
  • May source their product from those who shoplift from authorized resellers
  • May conceal their identity to avoid accountability or responsibility
  • May not accept returns or provide customer support
