Shop at the right places
In the age of corporate social responsibility, many businesses donate part of their proceeds to charities. For instance, AmazonSmile will donate 0.5% of your eligible purchases to a charitable organization of your choice, and Whole Foods gives you the option to donate your five-cent reusable bag credits to a local organization. Check with the merchants you shop at regularly to see if they offer opportunities to donate to an organization as part of your purchase.
