Sir, suppose A contracts with B that he will sell his cell phone to B for $1000 , but later he breached the contract. Then, B went to the market for purchasing the cell phone, and in the market he got 2 quotes , one for $1200 and the other for $1500. If B purchases the cell phone costing $1500 from the market, then how much damages he can claim from A in respect of breach of contract?
