The day after Thanksgiving, known as Black Friday, is the biggest shopping day of the year. One major retailer advertised a "Black Friday only" laptop for $150. On Thanksgiving night, hundreds of people waited for the store to open to take advantage of the laptop deal-only to learn that the store only had two units for sale at the discounted price. Did the retailer breach its contract with the hundreds of consumers who sought the deal? What obligation, if any, does the retailer have to its consumers?
