For those looking for a way to take advantage of the offer and having the magazines go to good use: another idea is to donate to school libraries.
I just contacted the NYC public school system and they were very excited about receiving magazines. You can call Sandy Bright at 718-935-4028. She will refer you to a school librarian. I just faxed over a list of all the magazines.
Given the selection of magazines, I'd probably recommend donating to a high school.
If you prefer, she can recommend specific boroughs as well.
