Product Retailers extension allows you to sell a product from other retail stores also. You can provide an option to either buy a product from your store or from other retail stores (of course you can use affiliate links). This plugin is also useful in case a product is out of stock in our store, this extension allows the customer to buy the product directly from the retailer website.
This is the EXACT same plugin as distributed by the developer on WooCommerce. The developers’ links are provided above.
