One World, Forward Thinking We are promotional product experts who are committed to your success. Here at MarketShare, not only do we want what is best for the customer, but we take a more global view. That is why we strive to use companies that are part of the Quality Certification Alliance (QCA). These companies follow standards that make them and their products safer, more environmentally friendly, and more mindful of social priorities. Similarly, we recognize the importance of ordering from US-made companies, and do so with frequency.
