Note: none of the below links should be affiliate links; Amazon does allow you to choose a listed charity or nonprofit on their Amazon Smile to designate to get the 0.5% donation. As I repeat below, you need to be using the Amazon Smile side of Amazon when you place the order for the charity to get the donation.
If you use Amazon on a regular basis and have a favorite nonprofit or charity, you may be to support the nonprofit through your Amazon purchases. There are around a million charities listed on Amazon that you can pick from which isn’t all of the nonprofits that are out there. Go to https://smile.amazon.com/ (not an affiliate link; alternatively you can switch http://www.amazon.com in your browser to smile.amazon.com by overwriting www with smile). It’s important to note you need to order on the Smile side of Amazon in order to generate the donation. Do a search on the charity you want to designate to receive the donation. Not everything qualifies, but many items do. Also, you do not pay more for any items that qualify than if you were using the regular Amazon side of the website.

Yes, you use the same account on Amazon.com and AmazonSmile. Your shopping cart, Wish List, wedding or baby registry, and other account settings are also the same.
How do I select a charitable organization to support when shopping on AmazonSmile?
On your first visit to AmazonSmile smile.amazon.com, you need to select a charitable organization to receive donations from eligible purchases before you begin shopping. We will remember your selection, and then every eligible purchase you make at smile.amazon.com will result in a donation.

Yes, you can change your charity any time. Your AmazonSmile purchases after the change count towards your newly selected charity. To change your charity, sign in to smile.amazon.com on your desktop or mobile phone browser and simply select “Change your Charity” in “Your Account.”

You can choose from over one million eligible 501(c)(3) public charitable organizations.
What if my selected charity does not register to participate in the AmazonSmile program or becomes ineligible?
If your selected charity does not register to participate, becomes ineligible, or requests to be removed from the program, you will have a chance to select a different charity to receive the accrued donations that have not yet been disbursed to your charity. If you do not select a different charity, the accrued donations will be distributed to other organizations receiving donations.
How much of my purchase does Amazon donate?
The AmazonSmile Foundation will donate 0.5% of the purchase price from your eligible AmazonSmile purchases. The purchase price is the amount paid for the item minus any rebates and excluding shipping & handling, gift-wrapping fees, taxes, or service charges. From time to time, we may offer special, limited time promotions that increase the donation amount on one or more products or services or provide for additional donations to charitable organizations. Special terms and restrictions may apply. Please see the relevant promotion for complete details.
Can I receive a tax deduction for amounts donated from my purchases on AmazonSmile?
Donations are made by the AmazonSmile Foundation and are not tax deductible by you.
While it’s normally only 0.5%, it can add up, especially if you get family and friends to choose the same nonprofit. Alternatively, you can spread the wealth between nonprofits by choosing a different nonprofit whenever you decide to change. Something to watch out for is to make sure you start and complete the order on the Smile side of Amazon. Switching back to the www side of Amazon before you complete the order may throw the system off and your chosen nonprofit wouldn’t get the donation.
If your nonprofit doesn’t participate, there is a way to nominate them as long as they meet the requirements Amazon has set for participating nonprofits. For example, I usually switch between a local historical/genealogical society, a local mental health nonprofit, and an area nonprofit where a family member works.
