Update: I just received these this week, so it took much longer than 4 weeks, but is a nice freebie!

One of the reasons I like free samples is that I can donate products to those who need them most.

If you know someone with a hearing problem, go to Hearing-Aid.com and register for free hearing aid batteries and an information guide from the National Council for Better Hearing.

This offer is for US residents only and should arrive in 2-4 weeks.
