Life moves pretty fast. If you don't stop and look around once in a while, you could miss re-ordering household products.

Amazon is now selling its Dash buttons to anyone with a Prime account. The palm-sized, Wi-Fi-connected devices let members order laundry detergent, water, and diapers with the touch of a button.

When it was announced just ahead of April Fool's Day, many thought the dash button was a joke. But it was real, and as of this week, no longer requires an invitation.

Just stick the gadget inside a kitchen cabinet, on the laundry machine, or next to the dog's food bowl. Then, when you're running low on supplies, tap the button to purchase trash bags, toilet paper, coffee refills, and more.

Eighteen popular brandsBounty, Tide, Cottonelle, Glad, Clorox, Gatorade, Maxwell House, Smartwater, Izze, Kraft, Larabar, Olay, Gillette, L'Oreal, Huggies, Gerber, Wellness, and, of course, Amazon Elementsare on sale now. Each button costs $4.99, and promises fast delivery for Prime members.

To ensure that your pet or child does not accidentally order you thousands of boxes of Huggies, you'll get an alert on your phone to confirm purchases. You also can't order another until the first order is delivered.

Last year, Amazon revealed a digital "magic wand," also dubbed the Amazon Dash, with a built-in barcode scanner and microphone that let users quickly add items to an AmazonFresh shopping list.

The e-retail giant, meanwhile, rolled out the red carpet for start-ups with its new Launchpad program that makes it easy for new companies to launch, market, and distribute merchandise to Amazon customers. More than 200 products are currently available in the Launchpad storeeverything from electronics to kitchen supplies to beauty items.
