Thank you for your message dated 22 May 2017.
We very much regret to inform you that we do not offer an option fo an international transfer free of charge for the sender. You basically only have the the possibility to choose between our cost and shared cost. In oder to save on fees we recommend you to chose the option our cost.
We thank you for your understanding and wish you a pleasant day.
If I remember correctly, someone already tried Our cost and saw it was worse than shared cost, or not? :-/
UPDATE: Wire from CH account to IB - #10 by T78a (20.- + 2.- for “our cost” option). Apparently they either are ignorant about their own costs, or are trying to push customers to costlier options.
