SanMar's Pack Separately. Ship Together (PSST) program is a collaboration between contract decorators and SanMar to offer high levels of service to Promotional Product Distributors (PPDs). Each day, SanMar consolidates multiple orders heading to the same address, eliminating the need for the PPDs to bundle orders and making it easier for contract decorator to know what's coming and when. While there is an investment required from contract decorators, the program is totally free to PPDs and offers significant savings and opportunities to both.
