This post will highlight a variety of non-traditional avenues through which you can donate to charitable causes at no monetary cost.

For each methodology I will note the following:

• What the donation requires (ex: a few minutes of time)
• What sort of cause the donation supports (ex: feeding the hungry)
• A link to the official site
• A link to a review of the charity (if possible)

Some of these methods are a simple as installing a browser extension or app on your computer! Take a look through the list and consider lending your time or computer hardware to a good cause today.
