I search for deals for a living and I've discovered the best space tech deals ahead of Fourth of July celebrations and Amazon Prime Day.

Amazon's best early Prime Day smart home bundle is the best-selling Ring Battery Doorbell with the Ring Indoor Cam for only $69.99 - a 50% discount. The smart doorbell features a built-in battery and, like the Ring Indoor Cam, enables you to see, hear, and speak with anyone from your phone or computer.

If you're looking for Amazon Prime Day deals, you'll need an Amazon Prime subscription. Using an Amazon Prime trial is a low-risk method for accessing the bargains while checking out the service's other benefits without being locked into something you may not be ready for.
