Little ways you give back or donate throughout the year

First of all, Happy Thanksgiving to everyone who celebrates. I'm thankful for all my friends here.

The holiday season is here, and I wanted to see if there are any charities you like donating to or if you have little ways you like to contribute to the less fortunate, even in very small ways.

Just an example of something small, whenever I'm on twitter I always RT the posts that are like "For every retweet we're giving a plate of food to someone in need" Or "For every like we're giving away a bag of dog food". It's hard to pass up.
