Can I also return my old phone and receive the 20 / 40 EUR recycling bonus when buying via a reseller? The terms and conditions aren’t particularly conclusive in that respect, imho. (And by the way: they are wrongly mentioning “the purchase of a Fairphone 2 smartphone” and “forty-five (45) Euro”.)
The application form you have to fill includes a field “order number” and that probably only works for purchases from Fairphone directly.
EDIT: I just stumbled across this thread where @BertG rightly states that the terms say you can only redeem a voucher on the FP webshop. Imho that still isn’t fully conclusive, too, as it only mentions the “redeeming the voucher” part and not when you get it. But I’ll shut up now and live with having to make the decision between supporting a reseller or getting 40 Euro.
[Still, updating the terms to the new process, where you can get the voucher after the purchase, and replacing “Fairphone 2” with “Fairphone 3” would make sense.]
