Ah, now I remember...I got waitlisted for the funds so I just went ahead and submitted my 5 schools. But--it did save me money on secondaries (NYIT, Touro-CA, and Western all waived it!).
According to the website: "If you receive a fee waiver, you may apply it to a maximum of three osteopathic colleges. If you receive a waiver, but wish to apply to more than three colleges, beginning with the fourth designation, you must pay the standard application fee. For example, to apply to one additional college (four total), you must pay the standard AACOMAS fee for one college; to apply to two additional colleges (five total), you must pay the standard fee for two colleges."
It's still a bit unclear, though.
