Bundling strategy is a popular marketing tool that the dominant supplier uses in supply chain and leads to the pros and cons. However, previous researches only focus on a retailer's bundling behavior. This paper innovatively studies a supplier's bundling policy of pure bundling and mixed bundling. Results show that the supplier's bundling behavior has a major impact on the supply chain and this effect is closely related to bundling strategy, while compared to pure components policy, pure bundling is disadvantageous to the entire supply chain and the supplier's profit and the retailer's profit both decrease. In addition, the retailer's order quantity and profit, the supplier's profit will be increased significantly under mixed bundling strategy, which is a ``win-win" strategy.
