Santiago Information Systems ("Santiago) is a business based in Baltimore, Maryland, that purchases old computers, refurbishes them with new software and hardware parts, and sells them in bulk for about half the price of a new PC. For the past three years. Santiago shipped approximately 40 percent of its inventory to the same client. The client was the Wilmington, Delaware. school system ("Wilmington") and the school paid approximately $80.000 to Santiago for the computers per year. Santiago would also visit each school to be sure that the computers were installed correctly and that the school district was satisfied with the order. Santiago has a Web site that gives contact information for the company, but is not interactive because users cannot transact business except for sending Santiago e-mail via the Web site. Recently, Wilmington has discovered that large shipments of Santiago's products were defective and they have been unable to come to a resolution with Santiago over the matter.

If Wilmington wishes to sue Santiago, what court(s) would have jurisdiction over this matter?
