Amazon Prime Day is well underway and you have until the end of play tonight, Tuesday 11 July, to grab yourself some incredible bargains. It ends at midnight and when the deals are gone, they're gone.

To get the deals you need to sign up for Prime membership, but you get 30-days free membership if you've not been a member before. Read more about it here.

It usually costs £79 a year (or £7.99 a month, if you can't stretch to the one-off payment).

Once you have membership, you'll be able to snag deals across the categories Amazon offers. Here then are some of the best UK deals available, by genre. We also include some tips and tricks below for first-time Prime Day bargain hunters:

Here are some rolling deals you can get on the build up to the day and through to the end of 11 July:

If you ask an Alexa-enabled device, such as an Amazon Echo or Amazon Dot, "Alexa, what are your deals?", not only do you get a two-hour heads up on many Prime Day deals, you can also get exclusive bargains.

Prime members who are yet to try Music Unlimited - Amazon's own music streaming service and rival to Spotify and Apple Music can do so on the cheap ahead of Prime Day. You can sign up for four months for the total cost of just £0.99. Read more about it here.

The service usually costs £7.99 a month for Prime members (or £79 a year on top of Prime membership).

Existing members who want to upgrade from the Echo-only plan - which costs £3.99 a month to stream from a single Echo or Dot - can currently save up to £30 a year when they step up to a Music Unlimited Family or Individual plan (£30 off Family plan, £10 off Individual). Read more about it here.

Those who want to upgrade to a Family Plan for the whole family to enjoy, from an Individual plan can also do so at a saving of £30 a year.

Whether you have a Music Unlimited subscription or just listen to the thousands of free-to-stream tracks as part of your Prime membership on Amazon Music, you are eligible for a chance to win one of 100 Amazon Echo speakers.

To enter, you just need to listen to one track on either Amazon Music or Amazon Music Unlimited up to the end of play 11 July. Each track you listen to will gain you one entry into the main prize draw per day. Only one entry is possible per day, no matter how long you listen, but you can do the same on the following day and so on until the end of the competition period. Read more about it here.

Until the end of play today, Prime members have the chance to win £100,000 in cash simply by streaming Amazon Video content to a television using a Fire TV, Fire TV Stick, games console or Smart TV app.

Prime members can get 40 per cent off a Kindle Unlimited subscription for the duration. The service usually costs £7.99 a month and gives access to millions of eBooks to read on a Kindle or through the Kindle app on a smartphone or tablet.

We will be adding more deals as we spot them throughout Amazon Prime Day, but you can check out these popular deal pages on Amazon (UK) to see if there is a deal for you already:

Amazon Prime costs £79 a year. You can, however, sign up for a free 30-day trial to get the deals. A neat trick is that you are fully entitled to cancel your Amazon Prime subscription after once you've got your shopping deal.

  • Amazon Prime free trial: UK
  • Amazon Prime free trial: US

As long as you cancel the trial before the end you won't be charged the £79 / $99 yearly subscription. Amazon hopes though that once you've enjoyed some of the benefits you won't hit the cancel button.

Get the dedicated Amazon shopping app on your mobile and turn on notifications.  Within the notifications settings you can turn on "Watched" and "Waitlisted Deals" so you don't miss it.

Get £1 back by opting for No-Rush Delivery if you don't need your new bargain straight away.

Rather than going in with a scattergun approach, make a list before you go onto Amazon and be targeted about the products you want. It might be July, but Amazon Prime Day is a perfect chance to do your Christmas shopping on the cheap.
