In case you've never done voice shopping before -- and we don't blame you; it sounds like a recipe for impulse buys -- you can also get $10 off on your first $20-and-up purchase through Alexa until the 12th. To buy anything through the voice assistant, though, you have to be a Prime member and enable one-click order ordering. Once you meet those criteria, you simply have to say "Alexa, order [product]" to make a purchase. Godspeed to you and your wallet.
