Tina's managing attorney gives her an even more challenging contract to review. This contract is between Wal-Mart and Amazon. The contract discusses how Wal-Mart and Amazon will jointly agree on the manufacturing and distribution of certain Barbie toys in the United States. They will each agree to only charge the same retail price on the Barbie Toys sold anywhere in the United States. Although unstated in the contract, Tina is aware the intent of Wal-Mart's business unit managers for toys is to ensure Wal-Mart can maintain a reasonable profit margin in an otherwise very competitive consumer segment and to help the managers ensure they get a big bonus at the end of the year for hitting profit targets. Tina has a bad feeling about this contract from something she learned in her paralegal courses. Identify what law Tina is concerned about Wal-Mart violating and explain whether you feel Tina's concern is justified or misplaced.
