I am looking for any old fairphone (in working order). Since my budget is 250€ max I doubt anyone would sell a fairphone 4 for that price, so looking for fairphone 2 or 3 (if someone has a Fairphone 1 that is working perfectly, then sure, but otherwise not interested since spare parts are not for sale anymore). Price I am willing to pay is obviously dependent on the model and its state (broken parts means I will have to buy them again so I will offer a lower price than if the phone works perfectly).
As most of you deduced from the first paragraph, price is strongly negotiable so if you have a fairphone for sale just PM me and we can talk!
NB: If you are interested and want to send a direct message, please check #how-to-dm.
Be aware, that cross-border shipment of batteries outside a phone is virtually impossible for individuals.
