A maker of perfume asks a manufacturer to supply 1,000 readily available glass bottles for retail sales. The manufacturer ships within five days. The perfumer pays $2.50 per bottle before receiving an invoice; the invoice later shows $3.50 per bottle. A court determines the reasonable price at delivery was $3.25 per bottle. What amount must be paid?

• A. $3.50
• B. $3.25
• C. $2.50
• D. $3.75

Answer: (B)

Under the UCC, when the contract leaves the price open, the price is the reasonable price at the time and place of delivery. Here, no fixed price was agreed upon for the 1,000 bottles. The perfumer’s prepayment and the later invoice don’t establish a binding price. A court can determine the applicable price, and it found the reasonable price at delivery to be 3.25 per bottle. Multiply by 1,000 bottles, and the amount due is 3,250. The buyer must pay 3,250.
