Abstract：Based on wholesale price contract and buy-back contract， respectively， price-postponement decision models are constructed for supply chain under uncertain demand. The existence and uniqueness of optimal order quantities under both contract conditions with price-postponement strategy are demonstrated by the unimodality of profit functions. Comparative and numerical analysis of two scenarios show that the optimal order quantity generated by buyback contract not only maximizes the profits of retailer and manufacturer to realize supply chain collaboration， but also effectively increases the order quantity of retailer so as to enhance the total benefit of the supply chain system compared with wholesale price contract. The advantage of the coordinated strategy of buyback contract with price-postponement is more significant， especially considering lower production cost， higher salvage value or higher wholesale price.
