Do I need to be a Prime member?

Technically, an Amazon Prime membership is required to access Prime Day deals. Don’t panic, though, because if you’re a new user, you can sign up for a 30-day free trial.

After the trial period, the subscription costs $139 annually or $14.99 per month, but you’re free to cancel anytime before the trial ends to avoid being charged.

What are the benefits of being a Prime member?

If you tend to make more than one order from Amazon each month, the likelihood is that it’s probably cheaper for you to sign-up to Prime to sidestep those additional shipping costs, which can really add up.

Other than free, next-day delivery, Prime members benefit from free streaming of movies, series, and live sports on Prime Video, plus ad-free access to Amazon Music and podcasts, along with use of Prime Gaming, Prime Reading, and Amazon Photos storage.

Let’s not forget, Prime members will get exclusive and early access to Prime Day Deals – so it’s worth signing up ahead of time. This includes 30min early access to Lightning Deals and to all the exclusive member-only deals during Prime Day(s).
