Compare refurbished and secondhand deals as you shop: save vs new, with warranty and returns from pro sellers. Before buying new, check whether the same product is available refurbished or secondhand, with a warranty and for less. Dero does it for you while you shop. BLACK FRIDAY AND CHRISTMAS: SAVE WITHOUT COMPROMISING ON QUALITY Phones, laptops, tablets, consoles, appliances, bikes, toys… Refurbished often costs much less than new. Giving refurbished is a great gift that saves money and is better for the planet. HOW IT WORKS? • Install Dero and shop as usual on your favorite sites • On a product page, the Dero button shows refurbished and secondhand offers for the same product. • Compare prices and condition, then buy directly from the seller you choose. WARRANTY AND RETURNS: Refurbished products from professional sellers are checked and restored before resale, and usually come with a 6-month to 2-year warranty (most often 12 months) depending on the seller. In France and the EU, online purchases from professional sellers can be returned within 14 days. Each seller shows its exact condition, warranty and return terms: check them before you buy. “SLEEP ON IT” Tempted by an impulse buy? Dero can email you a reminder later so you can decide whether you really need it.
