Amazon’s best-kept secret is AmazonSmile, a simple and effective way to support just about any charity, including WHCP. Whenever you make an eligible purchase, the shopping giant will donate to 0.5 percent of the total price to that charity.

Just point your browser to smile.amazon.com, then specify WHCP as the charity you want to support. Then just shop like normal. All prices and products are the same as they would be otherwise; this is the easiest charitable giving you’ll ever do.
