you know... after reading the OP i realise that
this is the usual mistake that let you think that FD is not very experienced in marketing and dealing with the customers.
the big lesson missed here is: ''simply you can't leave any kind of misunderstanding in what you write on newsletters and into the advertisements.''
I would wager this is their true greatest failing, far beyond programming or design anything. Their marketing is full of this kind of vaguery since forever. This isn't THE example but it's indicative of the marketing in general.
