Even better? It works with Amazon affiliate links to, so if you click through an Amazon link on my page to Amazon Smile, your price stays the same, but both your charity of choice and the my family get a tiny chunk of Amazon's profits!
To get to Amazon Smile, either click through a link like that one(which would allow you to also support your favorite blogger!), type smile.amazon.com into your navigation bar, bookmark smile.amazon.com, or from any regular amazon page, change "www" to "smile". Some products, like subscriptions for monthly delivery of certain products, don't qualify, but most do.
I think its awesome that Amazon is making it easy to support your favorite bloggers and your favorite charities when doing your usual shopping and without any additional costs to you. Yay Amazon!
