Fairphone 4 New Life Edition with free Longevity Bundle
Refurbished FP4 can again be bought with a Longevity Bundle (screen protector + case) added at no extra cost. 128 GB / 6 GB and green speckled versions out of stock.
P.S.: Not a promotional deal, but a significant extra incentive: FP4 purchases in 2024 and 2025 now qualify for the extended 2+3 years warranty, too (see point 2.3 in the legal smallprint) 
This was formerly limited to purchases until 31 December 2023.
22 January 2024: Refurbished FP4 apparently (at least currently) sold out – no longer in the shop.
