Platinum Shield Association Says Early Promises False and Seeks Day in Court With UPS to Make Future Secure - Reuters The UPS Stores have also brought suit against MBE and UPS for misrepresentations made to convince franchisees like Martinez to convert their MBE Centers to The UPS Stores. UPS Store franchisees won a major court decision last October, when a California appellate court overturned a lower court and certified their lawsuit against UPS as a class action. At present there are four lawsuits filed against UPS by various store owner groups across the country based on the forced conversion of the successful Mail Boxes Etc. business model to the failed UPS Store model. If successful, the end result could be the undoing of this conversion of approximately 3,400 UPS Store franchise locations.
