Prime Day is done. Now here's what's about to charge you.

Prime Day 2026 ended four days ago. The headline deals on TVs, headphones, and kitchen gadgets were genuinely worth it for many families. But buried in the offer pages were subscription trials and introductory prices — and the clocks on those are now ticking.

64.8% of people who sign up for a free trial forget to cancel before being charged. After a four-day deal event crammed with signing-up prompts, that number will be even higher.

Here's what you almost certainly clicked, and what to do about it right now.

What you (probably) signed up for

Amazon doesn't just sell products during Prime Day — the event is its biggest subscription acquisition window of the year. Here's the standard lineup that ran alongside the deals:

Amazon Prime itself. To access any Prime Day deal, you need a Prime membership. If you started a fresh 30-day free trial on 23 June, your trial ends around 23 July. After that: £14.99/month or £139/year. If you already subscribe annually, no action needed — but if you started monthly to "just check out the sale", you're billed in about three weeks.

Kindle Unlimited — 3-month free trial. Normally £9.99/month. Trial runs until roughly 23 September. That lands right in the school return window when your budget is already stretched.

Amazon Music Unlimited — 4-month free trial. Normally £10.99/month. Trial ends around 23 October. The longest fuse of the lot — easy to forget because it feels so far away in June.

Prime Video channel add-ons at £0.99/2 months. This is where it gets messy. Channels like Paramount+, MGM+, Apple TV+, Starz, and Fox One were all offered at £0.99 for two months. After that, each one auto-renews at its full price: typically £4.99–£8.99/month per channel. If your family clicked three of those offers, you could be looking at an extra £15–27/month appearing quietly from late August.

When the charges hit

The August dates are worth flagging. Many families are on holiday in August — spending on accommodation, food, and activities — and that's exactly when three or four streaming add-ons will start silently charging full price.

What to do in the next ten minutes

Step 1: Search your inbox. Open your email and search for "Amazon" with a date filter of 23–26 June 2026. Every subscription trial you started will have a confirmation email. Make a list.

Step 2: Log each one in SubManager. Add each service with the trial end date (or intro pricing end date). SubManager will send you a renewal alert 7 days before each one ends — enough time to decide whether to keep it or cancel without the charge hitting by surprise.

Step 3: Decide now, not later. It's much easier to cancel in a calm moment today than to try and remember in mid-August when you're three days into a family holiday. Each service has a "Manage subscription" option in your Amazon account under Account & Lists → Memberships & Subscriptions.

Which ones are actually worth keeping?

Kindle Unlimited: If your family has kids who read in summer, three months of unlimited ebooks is a genuinely good deal. Just set a reminder for mid-September. If nobody used it, cancel now and save the October-surprise.

Music Unlimited: Not worth keeping if you already have Spotify, Apple Music, or YouTube Premium. Adding a fourth music service nobody asked for is pure waste. Cancel it today.

Prime Video channels: Be honest with yourself — did your family actually plan to watch the content on that channel, or did you click £0.99 because £0.99 felt like nothing? Starz for two months is fine if you're finishing a specific show. But if you signed up speculatively, cancel before August.

Prime itself: If your household orders from Amazon regularly, Prime pays for itself quickly. If you started the trial just for Prime Day access and rarely order, the monthly tier at £14.99 isn't a great deal — switch to the annual plan or cancel before 23 July.

The actual maths

If you signed up for Prime (monthly), Kindle Unlimited, Music Unlimited, and three Prime Video channels during Prime Day and forget to cancel all of them, you'll be paying an extra £55.95/month by autumn. That's nearly £670/year for services you grabbed in a four-day sale frenzy.

No deal is a good deal if you keep paying for it forever.

What's next

Take ten minutes this week to check your Amazon subscriptions. Open SubManager, add the ones you want to keep with their trial end dates, and cancel the ones that were impulse sign-ups. The deals were real — the forgotten renewals don't have to be.
