Do I need to be a Prime member?

Yes – technically, you’ll need an Amazon Prime membership to get access to the deals. But don’t stress, if you’re new to Prime you can sign up for a free 30-day trial, which gives you full access to all the Prime Big Deal Day discounts without spending a single penny (unless you choose to, of course).

After that, the subscription costs £8.99 per month or £95 annually, if you choose to continue your membership.

What are the benefits of Prime membership?

Aside from early access to Prime Day bargains (including 30-minute early access to Lightning Deals), there’s a whole host of perks that come with being a Prime member.

These include free next-day delivery on thousands of items, access to Prime Video with its solid library of films, TV series, and live sport, and ad-free listening through Amazon Music.

Members can also enjoy Prime Reading, with a wide range of books and magazines, as well as Prime Gaming and Amazon Photos for gamers and photography enthusiasts alike.

If you regularly order kit, nutrition, or the odd last-minute race-day essential, it’s probably worth it just for the free delivery alone.
