It Wasn’t an April Fools’ Joke: Amazon Dash Buttons Are Available Now for $5

But will anybody buy them?

Amazon's Dash buttons are here, going on sale on the e-commerce giant's website today for $5 each.

Eighteen brands are offering the buttons, which let consumers place them around the house, press the button and instantly re-order products like toilet paper and coffee. The small, plastic buttons are wired to the Amazon Prime smartphone app, allowing users to control purchasing restrictions, such as quantity, while stocking up on Gatorade, Gerber, Tide, Huggies, Kraft, Glad and other products.

The buttons were first announced March 31, prompting many to wonder if they were an early April Fools' Day joke. They were not, though whether people actually buy them, put them up in their homes and use them is another matter altogether.

Adam Padilla, creative director at BrandFire, said he believed they would when the buttons were announced three months ago.

"Maybe I am drinking the Kool-Aid," he told Adweek at the time. "But I think it's obviously very smart and also has practical use cases."

Stay tuned.
