If you're already subscribed to Amazon Prime, you might have heard of Amazon Prime Channels, a feature on the platform that allows you to add standalone services and channels to your existing subscription for a fee. So instead of having multiple separate services, with Amazon Prime Channels, you can access them all on a single platform and pay for them on a single bill.
Add-ons are not necessarily cheaper, but Prime offers bundles that you can get for a discounted price. For example, if you want to get AMC+ and Starz (premium channels on traditional cable, mind you), you'll have to pay $8.99/month for each separately. But if you get them as add-ons, Prime offers a bundle that lets you combine them for $13.99/month, shaving off $4 in the process.
As of this writing, there are over a hundred channels you can choose from on Prime, but here, we've simplified the search for you and narrowed it down to the best add-ons that are worth your time.
