Actually, you need to do more than just smile. You have to sign up for Amazon Smile (smile.amazon.com) and identify a charity to receive a small percentage of the cost of each purchase you make there. Amazon Smile is exactly the same as the regular Amazon in all respects except for the donation it makes on your behalf. Typically, the donation is 0.5% but there seem to be bigger percentages announced on occasion. The accompanying image reports that $13.99 was donated to the Ann Arbor Rotary Foundation (EIN: 38-6092093) based on one quarter of purchases this summer. While the amount of each donation may not be much, every little bit helps and the ongoing cost to the donor in time or dollars is zero!
