Givv.org - interesting approach to manage your donations
givv.org
givv.org
An added benefit is that they can give you a single statement for your taxes. I assume that, from the IRS's perspective, you are just giving to givv.org, a non-profit.
They don't state this on their website, and they claim you can give to anyone, not just charities, which makes me wonder if you lose the tax-deductibility by using givv.
