Edward, a professional computer consultant who evaluates and purchases computers, agreed to purchase approximately $10,000 worth of computer hardware from Forks Computers, Inc, owned by Isabella. Forks customarily includes a one-time setup service visit estimated at $1000 in value. Isabella had offered to sell the hardware and provide the setup for $11,000. Edward felt that $11,000 was too much, but he mailed a signed purchase order to Isabella for $10,000 for "computers to be delivered." Isabella did not read the PO when she received it, and delivered set up the computers. Edward paid $10,000. Isabella then billed Edward an additional $1,000. Edward refuses payment, and Isabella threatens legal action. Discuss the parties' likely basis for relief and whether this contract is governed by the UCC.
