A cordless vacuum is one of those splurges that will make you wonder how you ever lived without it. The $170 Vipsun Cordless Vacuum Cleaner is on sale for $90 for Prime Day. One shopper loves it so much, they tout, "I'm a repeat Dyson buyer: choose this one instead."

Sales are like a sugar addiction for consumers.

The Arlo Video Doorbell (2nd Gen) is extremely easy to set up without needing any wires, just slap it on your door and you're good to go.
