Just a quick note from one of my LSAT students who asked for (and received!) several application fee waivers this cycle:
Thanks for the help with my fee waiver memo. I got waivers at Duke, Georgetown, Boston University, Cornell, University of Virginia, American, and Columbia. I also got a few more fee waivers after my LSAT scores posted. Definitely saved me over $1000. Got snubbed by NYU, Fordham, Stanford, UC Berkeley. They all encouraged me to apply for a need based fee waiver through their website.
As noted previously on this site, law schools are desperate for your applications (especially this year!) and many will let you apply for free if you simply ask them. Read this post if you want to know more.
Have you asked for fee waivers? What have you heard?
