Amazon Prime Big Deal Days 2025: the last day of deals on headphones, TVs, speakers, home cinema and more

It's Amazon's autumn sale, essentially another Black Friday but in October instead of November.

Prime Day began in 2015 as a celebration of Amazon's 20th anniversary. While other online retailers get involved in the Black Friday bargain bun fight, Prime Big Deal Days is generally all about Amazon, though you will see other retailers lowering prices at the same time in order to stay competitive.

Prime Big Deal Days is a big sale that encompasses most areas of the Amazon site – as well as audio-visual gear, you'll find discounts on toasters, books, clothes, and pretty much anything that Amazon sells. And that's a lot!

This year, the sale takes place over two days. But the deals can go on for weeks.

You'll need to be a Prime member to take advantage of the offers. Not yet a member? Amazon Prime's free trial gives you the option to sign up, bag a few bargains on Prime Big Deal Days, and cancel your membership without paying a penny. You scallywag, you.

Amazon Prime Big Deal Days 2025 starts at 00:00 on Tuesday 7th October.

Amazon Prime Big Deal Days 2025 finishes at 23.59 on Wednesday 8th October.

1. Sign up for the free Prime trial
If you're new to Amazon Prime, make sure you take advantage of the 30-day free Prime trial. And remember to cancel if you don't want a monthly bill for £8.99 when the trial ends.

2. Google a product before buying
Not every deal is going to be a winner, so make sure you compare prices online before you buy, and, of course, check our reviews to make sure the product is worth buying at all!

3. Big brands can equal big savings
Amazon often slashes the cost of a few big brand items – think PlayStation and Xbox accessories, Samsung TVs and tablets, etc – to get the attention of shoppers. Keep an eye out for these 'marquee' deals.

4. Check the Amazon Warehouse
Returned goods end up on sale at the Amazon Warehouse at a decent discount, so there's a chance you could spot an open-box bargain that beats the box-fresh sales price.

5. Stay tuned to What Hi-Fi.com
Amazon unleashes thousands of deals around Prime Big Deal Days, which can make it tricky to find genuine bargains on five-star tech and AV. That's why we'll be publishing an up-to-the minute list of the very best Prime Big Deal Days 2025 deals.

Technically, yes, but Amazon's other sales are near-identical, but just go by different names. Prime Day takes place in the summer, Prime Big Deal Days happens in the autumn, then Black Friday is at the end of November. Prime Spring Deal Days kicks off the sales year around March or April.

We're expecting plenty of deals on all kinds of devices, including headphones, TVs, Bluetooth speakers, cables, hi-fi and smartphones from big brands like Sony, Samsung, Bose, JBL, Bang & Olufsen, Apple and Sonos.

But beware: not all that glitters is gold. Some discounts might seem hefty, but they might have been bettered previously, or be on sub-par products. We'll only feature deals that offer a worthwhile amount of money off on products that we recommend.

Without Prime, you can't take advantage of the discounts. There are all sorts of other benefits to Prime year round, like early access to 'Lightning deals', Prime Video and Amazon Music streaming, and try before you buy on certain items. Here's a list of more Prime benefits.

It is, as long as you have signed up for Amazon Prime. No Prime, no deals. You can pay for Prime monthly (£8.99) or yearly (£95).
