update for everyone:

y'all was wrong. I axed many of the schools that were sending me solicitations that I did not plan on applying to. Most said no, but one said yes. Schools do in fact offer CAS reporting fee waivers, for anyone interested.

If you plan to apply to a lot of schools, I'd say there is NO harm in asking. It's an innocent enough question and totally not presumptuous.

PS: The school that said yes was a top US News top 50.
