This crap is all made in China! Someone is suckering Americans by fronting that they donate to charities! 8% is all that's donated... the bare minimum! That's so they can use that they are a charity to avoid paying taxes!
Come on people... don't be suckers! These A-holes are just scammers! Believe that!

It is a scam most probably. There is no privacy when a charity is concerned so if they cannot provide any legitimate answer to your question, don't waste your money here.

I'm sure GreaterGood.com sends the money to general charity funds rather than buying food, books, etc., themselves, which means it would be up to the charity funds that purchase and deliver those items to post pictures on their own sites, not GreaterGood.com. And I bet privacy policies also factor into it.
