Earlier today I posted about a promotion that lets you buy Amazon Dash buttons for $0.99 each and still get a $4.99 credit when you use the button the first time. It turns out that there isn’t just one promo code that works, but several different promo codes. Even better is that the different codes stack on each other, so if you apply more than one code to a single order, it will make the Dash button completely free. You’ll even still get the full $4.99 credit when you use the button for the first time. The promo codes even work on the $20 AWS IoT Dash button meant for programmers and developers. I was able to stack several promo codes to get an IoT button and regular Dash button for free in a single order (screenshot). The stacking of codes is likely an unintended bug with this promo, so order soon because I exepect it will be disabled soon.
Promo codes to try at checkout are: RMNBUTTONS, SLICKBUTTONS, ZIFFBUTTONS, REVIEWDASH, COLLECTDASH, KINJADASH, IDGDASH, BGRBUTTONS
