I got this e-mail in one of my eighteen e-mail accounts that gives an idea for the best Valentine's Day gift idea ever.
a sewing machine for a Dalit woman,
vaccines for Dalit children,
training for a Dalit Education Center teacher,
tools for a Community Healthcare Worker
and many more options!"
This organization called the Dalit Freedom Network advocates for the Dalits (those lowest in the social caste system) in India. http://www.dalitnetwork.org/go?/dfn/resources/C128/
The gifts range in price from $15 to thousands of dollars...so I'm sure there is something to fit in your price range :)
