Hi @sebastien - thanks for the question.
The request for SBD came from @stellabelle directly. And when the woman with the #1 reputation score has a specific request, my thought is: you don't try to negotiate too much.
Perhaps she can weigh in on your question regarding why it was that she asked specifically for SBD to be transferred :)
ha ha! Wise move! No, really, you're free to do whatever you wish as am I.
