Amazon's Prime member service has almost become synonymous with the company and comes with dozens of perks. I won't try to sell you a membership, but if you order from Amazon multiple times a month, a Prime membership will bring tons of value. There's certainly a reason more than 100 million people have invested in the service.
You can share an Amazon Prime membership with one other adult, and kids who share the account can access perks like Amazon Prime Instant Video. Amazon Family provides a 20% discount on diapers, baby food, and household items.
If you're a student, you can use an email ending in .edu to sign up for Amazon Prime Student. The service offers a six-month trial and costs $6.49 a month after that. People receiving Medicaid or EBT benefits are also eligible for a discounted Prime membership at $5.99 per month.
