I'm a little skeptical about this as there are some things that I noticed that are questionable. They state that the point value is tax deductible. I went to the ClickRewards website and visited the charities that they work with. The charities' website state the point value is not deductible. UNLESS the reason is the points are ClickRewards and not AA points, possibly the reason. The quality of the website leaves doubt also, a little amateurish.
Some of the websites accept credit cards which gives an added bonus if you use one that is tied to an airline plus the protection of a credit card.
If in doubt check with the New Jersey Attorney General. Since it's on the Internet it's also a federal matter so the FTC/FCC can investigate if necessary. You could always ask to see a copy of their financial statements. If they hesitate start asking questions. The thing with ClickDough is a little cheesy, has the appearance of an MLM scheme.
Don't knock it unless you really check behind the doors, could be a viable organization, 'specially if you are Irish-American.
