For this question only, assume that BallCo did send SportCo a copy of its 2019 catalog, but that SportCo never examined it. When BallCo insists that SportCo must buy the baseballs, SportCo agrees and stands ready to pay $288 per gross. BallCo demands $319, the price set forth in its 2019 catalog. All other facts are as originally set forth. Probably, BallCo is entitled to be paid
A.$288, because that is the price it has repeatedly charged SportCo, and SportCo had no actual knowledge of the price change.
B.$288, because it is unreasonable suddenly to publish a higher price to a long-time buyer who has customarily and in good faith paid a lower one.
C.$319, because under these circumstances a buyer should reasonably expect to pay according to a seller's published price list.
D.nothing, because a buyer need not pay a price to which he has not agreed.
