If you shop with an AmazonSmile account, you can automatically donate 0.05% of the purchase price to your favorite charity WITHOUT ANY ADDITIONAL cost to you.
Just click on the above Get Started button or go to smile.amazon.com, sign into your amazon account, and scroll down a little to type in a specific charity name, such as Next Step Service Dogs (our favorite of course, hope it will be yours too!). It will automatically donate to your selected charity indefinitely and is easily changed whenever you wish. Super!
