The Amazon Dash buttons actually were announced as an April Fool's joke, but have turned out to be a great product. And right now, the company has discounted all of their Dash buttons from $4.99 to $1.99 each. Which should help everyone stock up on the ones that they need. Additionally, you can still get a $5 credit on each Dash button after your first press. Which means Amazon is basically paying you to buy these buttons. So you might as well pick one up.
Amazon Dash is pretty simple. You set up the Dash buttons to your account and to a specific product. Say you pick up the Tide button for ordering more laundry detergent. Every time you press that button, Amazon will automatically re-order your Tide laundry detergent and it'll be at your home within two days. It's just that simple. You can mount these Dash buttons around your home, making it easy to buy things as you run out of them. Because we always forget something when we go to the store. Of course you will need Amazon Prime to take full advantage of Dash, which you can sign up for a 30-day trial (students get 6 months!) using the links below.
