Retail trade-in is a process where customers can exchange their used items, such as electronics or clothing, for store credit or discounts on new purchases. This practice allows retailers to resell the traded-in items, often after refurbishing or cleaning them, which can be more sustainable than simply discarding them. Many retailers, including electronics stores and clothing brands, offer trade-in programs to encourage customers to upgrade their products while reducing waste. Customers benefit by receiving a financial incentive, making it easier to afford new items, while retailers can attract more shoppers and promote eco-friendly practices.
