So the basics of this deal for Amazon Prime members are pretty simple. Amazon normally sells their Dash Buttons for $4.99, but they're currently offering them for $0.99 AND you get a $4.99 Amazon credit towards whatever product your button orders! So basically you get the button plus $4 to go towards something you know you'll need later on, from toilet paper to coffee to countless other everyday household items. At the very least you could only use it once and put it away until the next promotion rolls around!
If you're unfamiliar, Amazon Dash buttons are little wi-fi devices that are meant to go around your home. They're meant to make it easier for you to reorder your usual items by the push of a single button. I signed up for a paper towel Dash button and plan on sticking it inside my kitchen cabinet where I store my extra towels. Now comes the fun part of seeing if I can manage to literally push a single button before I run out. Vegas has me as a 2-to-1 underdog!
Note in order to receive your free $4.99 credit, you must use the Dash button once before the end of this year.
