“What is AmazonSmile?
AmazonSmile is a simple and automatic way for you to support your favorite charitable organization every time you shop, at no cost to you. When you shop at smile.amazon.com, you’ll find the exact same low prices, vast selection and convenient shopping experience as Amazon.com, with the added bonus that Amazon will donate a portion of the purchase price to your favorite charitable organization. You can choose from nearly one million organizations to support.”
My experience: it was very easy to set up. I was pleasantly surprised to see Subud Pacific Northwest on the list of eligible charities. Anyone who uses Amazon just has to go to the website above and they will be asked to pick a charity. So far, everything I have purchased (books, supplements, etc.) is eligible and Amazon just takes the .5% out of the normal price I pay for the item. This costs me, the consumer, nothing but a bit of time for the extra step to go directly to AmazonSmile instead of the general Amazon site. As far as I can tell, there is no difference between the stock available on both sites.
