Amazon’s Dash Button birthday sale was supposed to end yesterday, but it’s still going strong if you haven’t taken advantage yet.
Until the deal ends, you can buy up to three Dash buttons of your choice for $1 each with promo code DASHBDAY. And as always, the first time you use them to order an item from Amazon, you’ll automatically receive a $5 discount. That basically means if you maximize this deal and use all three, you’ll be getting $12 worth of value essentially for free.
