A school board contacts Furniture Manufacturing Inc. and presents them with exact specifications for special, space saving, stackable chairs they can use in the gym when there is a school assembly. The manufacturer looks over the drawings and specifications and several days later contacts the school board with a price that seems to fit the school board's budget. They agree on the price and also agree to accept delivery within a reasonable time for manufacture within four months.

Scenario one: When the chairs are delivered they immediately discover that the chairs topple over when someone takes a seat. The school board refused to pay.

Scenario two: Two: Furniture Manufacturing Inc. cannot make delivery within 4 months and asks for a 3 month extension.
