Amazon's four-year dalliance with plastic "BUY! BUY! BUY!" buttons appears to finally be coming to a close.

The Amazon Dash line of physical, Internet-connected buttons, which allowed customers to purchase (usually for around $5 a pop) one-tap restocking of home staples like snacks, toiletries, and laundry supplies, will stop functioning altogether on August 31. This follows Amazon's decision to stop selling the buttons in February of this year, despite being so bullish about the concept that it was selling over 100 brands' worth of Dash buttons by 2016.
