Martin Luther King Monday has become a day of service in many parts of America. This national holiday, which honors the civil rights’ leader’s birthday and is held each year on the third Monday of January, usually means a day off for school children and workers alike, giving them a chance to give back in one way or another.

If you haven’t signed up to help a good cause today, here’s one way you can help: make today the day that you bring donations to your local church thrift store or soup pantry, or good causes with retail locations, like Goodwill and The Salvation Army.

I’m sure you’ve done some cleaning out of the closets after the holidays–maybe your kids got new clothes and so you culled their old stuff to make room for the new. If so, make it a priority today to donate those clothes to an organization that can sell them and help to support itself. Maybe while you’re at a place like Goodwill, you’ll do a little shopping for yourself, too.

Talk about your win-win: you can come away with a tax deduction for your donation and provide funds (by shopping) for some very worthy causes.
