What happens to your old product when you don’t need it anymore? Buying a new product is not a problem. Selling your old one is. Fairown Buyback takes the hassle out of resale. We buy the product, fix it up nicely, and find a good use for it. Fairown Buyback is a combined system of credit and buyback. We give customers more choice and take away the hassle of getting rid of the products they no longer need. For merchants, we unlock the benefits of recommerce. * Increased business predictability with returning customers and repetitive purchases. * Decreased environmental impact by extending the useful life of products. * Additional new business by selling refurbished products. Fairown operates in nine markets across Europe. Our buyback service is used by ~100,000 consumers and awarded by leading financial experts at Asset Finance Connect. Fairown works with leading brands that are shifting from a linear to a circular economy. For example, STIHL, Komplett, Apple Premium Resellers, and more.
