AmazonSmile is a website operated by Amazon with the same products, prices, and shopping features as Amazon.com. The difference is that when you shop on AmazonSmile, the AmazonSmile Foundation will donate 0.5% of the purchase price of eligible products to the charitable organization of your choice.
Another way to donate while shopping is with Giving Assistant. Giving Assistant's mission is to transform everyday shopping into charitable action. Visit https://givingassistant.org/np#palm and shop from there.
