Alexa can do a lot of things without Prime. She can control your smart home devices, she can play music, she can answer your questions, and she can even order you a pizza. However, if you want to use Alexa to her full potential, you’ll need a Prime membership. With Prime, you can ask Alexa to do things like order groceries, schedule appointments, and even track your package delivery. Prime members also get access to a variety of exclusive deals and discounts.
