Donate through Amazon Smile everytime you purchase a book through Product Hunt.
This #1DayHack was inspired by a tweet convo w/ @AndrewDixonSo thanks to his conscientious use of an Amazon Smile Link when he hunted Insanely Simple.
Using smile.amazon.com 0.5% of your purchase goes to charity.

It's easy to forget to smile, especially when rushing to be first to hunt a book.
With Smile Hunt a "…With a 😄" button is added that will redirect you to the smile version of the book.
