Tide Dash Button | $2 | Amazon | $5 credit on first use

Putting aside the moral issues of giving teenagers one-click access to infinite, unregulated Tide Pods, this Dash Button is a really great deal. You just pay $2 for a Tide Dash Button, configure it to order your favorite detergent product, and you’ll get a $5 credit the first time you use it. That’s basically like a $3 discount on detergent.
