Use the above link pick a 2A organization that is affiliated with Amazon Smile and when you buy something that is a qualifying item you donate to your chosen organization.
I'm not sure if anyone knows about this, but as you can see it helps. Over 334k went to the 2A Foundation so far, and over 29k this quarter.
If INGO or other Indiana 2A organizations are available post them so we can support a local 2A group.
