Office Supplies Departmental office supplies must be purchased via Drexel Smart Source. Shoppers/Requesters simply login via the employee tab on DrexelOne and shop online. Phone orders will not be accepted. Purchase Orders are issued to the supplier so it is no longer necessary to select cost center information in Telrose/Office Depot. Moreover, it is no longer necessary to set up accounts or maintain separate login credentials. Best Values Items specifically discounted for Drexel are marked with symbol Returns Returns should be coordinated with Telrose Customer Service directly. Your return pickup will be scheduled to coincide with your next delivery or within 5 days if no orders are scheduled.
