Donating to charity by shopping at Amazon
Amazon has a cool program called AmazonSmile. Whenever you shop through AmazonSmile, they’ll donate 0.5% of your purchase to the charity of your choice. They have just about every charity you can think of, including the LDS church.
The prices at AmazonSmile are the same as at the normal Amazon site, but your charity will only get the donation if you use the AmazonSmile site. To make sure I’m always on the right site, I installed the Chrome Smile Always extension. It is also free, and magically changes any normal Amazon link you go to into an AmazonSmile link.
