Why buying refurbished is better than buying new 

Choosing a refurbished device over a brand new one is a smart choice for your wallet and a great choice for the planet. The manufacturing of new devices, like the latest Samsung Galaxy S25 series, releases a significant amount of CO2 emissions. In fact, 80% of a smartphone's total CO2 emissions come from the manufacturing process. By buying a refurbished smartphone, you're actively combating climate change by reducing the demand for new manufacturing, thereby preventing a significant amount of CO2 from being released into the atmosphere. The simple switch from new to refurbished contributes to a sustainable tech industry, lowering your carbon footprint while still getting first-rate tech at a pocket-friendly cost. Back Market's Verified Refurbished devices are refurbished by certified industry professionals to premium working condition and are offered at up to 50% less than the cost of a new device. For added peace of mind, you get a 30-day return period and a 1-year warranty with every purchase.
