Flint, a retail seller of television sets, orders one hundred Color-X sets from manufacturer Martin. The order specifies the price and that the television sets are to be shipped by Hummingbird Express on or before October 30. Martin receives the order on October 5. On October 8, Martin writes Flint a letter indicating that the order was received and that the sets will be shipped as directed, at the specified price. Flint receives the letter on October 10. On October 28, Martin, in preparing the shipment, discovers it has only ninety Color-X sets in stock. Martin ships the ninety Color-X sets and ten television sets of a different model, clearly stating on the invoice that the other ten are being shipped only as an accommodation. Flint claims Martin is in breach of contract. Martin claims the shipment was not an acceptance and, therefore, no contract was formed. You are the judge in this case.
