Do you use Firefox? Do you shop online? Do you have something other than black coal in your chest?
Let me introduce you to Browse for a Cause. The jist of it is, many online retailers (like Amazon.com) will pay a referral percentage to the website that sent you to Amazon (usually around 3-5%). If you go directly to the site, they don’t pay that money to anyone. What this Firefox extension does, is insert itself automatically as the “referral site” to the online retailer so that money will go to the charity of your choice. You pay the same either way, but you can help out!
If you still don’t get it, watch this:

Now, what if you don’t have a specific charity in mind? Don’t go giving money willy-nilly to anyone claiming to be a charity..do some research here: CharityNavigator.org. You can look up a charity by name or cause, and see how much of the money they are given actually goes to helping the cause.
