If you have a credit card that has cash-back bonuses on it that give you a percentage of your charges back in the form of credit or cash, here's some good news: The bonuses are not taxable income, according to the IRS. But here's even better news: If you choose to donate your cash-back money to a nonprofit, that money is tax deductible. Save money, help a cause and do it all without really trying too hard.

We all recycle, but there are ways to make it easier and more efficient. Labels on glass bottles and jars do not need to be removed; in fact, they help keep the bottles intact and prevent breakage. When glass is recycled, the labels are removed or burnt off during the melting process. If you happen to set your flattened cardboard boxes out at night and it rains, no need to worry; wet cardboard is still recyclable. Finally, make room in your recycling bin by crushing aluminum cans. They are still recyclable, and it frees up space for bulkier items.

When you explore the beautiful natural landscapes of another country while traveling abroad, be sure to have your hiking boots cleaned before you head to the airport for your return flight. The deep treads of hiking boots can be filled with contaminated soil, seeds and other items that create a "biosecurity risk" by bringing non-endemic species into the United States. U.S. Customs flags people who wear hiking boots home, so be sure to scrub them clean or face an inspection -- or worse, be forced to toss them.
