Abstract: In a method of facilitating product exchange transactions, an exchange facilitation system uses product return transaction data to establish a machine learning-based return transaction model using. The exchange facilitation system receives a request to purchase a desired product from a first purchaser user device. The exchange facilitation system determines an exchange offer recommendation using the machine learning-based return transaction model and information from the request to purchase. The recommendation includes an exchange offer including a proposed wait interval duration. The exchange facilitation system transmits the exchange offer to and receives an exchange offer response back from the first purchaser user device. Responsive to receiving a positive exchange offer response, the exchange facilitation system initiates a product exchange wait interval limited to the wait interval duration.
