Right now if you buy a Dash Button, Amazon will give you one for free in honor of National Pet Week, this week. But they’re still giving you the $4.99 credit after the first time you use it. So that’s two Dash buttons for free, really (typically Dash buttons cost $4.99). Amazon Dash is a simple Wi-Fi connected gadget that lets you order your favorite things with just the push of a button. Keep it by your washing machine, your pet food, or in the bathroom closet. When you notice you’re running low, just press the button and Amazon ships it right out. Each button gets tied to a specific product from Amazon’s library of over 300 brands, in categories such as (click each category to see samples) household supplies, beverage & grocery, health & personal care, beauty products, pets, kids & baby, and more.
