How Amazon smile works
Login to your regular Amazon account via https://smile.amazon.com/
It is STILL the Amazon you know and love! This is a way that Amazon helps customers give back to charities through the Amazon Foundation.
AmazonSmile is a website operated by Amazon with the same products, prices, and shopping features as Amazon.com. The difference is that when you shop on AmazonSmile, the AmazonSmile Foundation will donate 0.5% of the purchase price of eligible products to the charitable organization of your choice.
Every item available for purchase on www.amazon.com is also available on AmazonSmile (smile.amazon.com) at the same price. You will see eligible products marked "Eligible for AmazonSmile donation" on their product detail pages.
