About black friday
Black Friday is usually the biggest filament sale of the year on Amazon UK, with multipacks and big-brand reels often at their lowest prices. It is also when “was” prices are least trustworthy.
Every price on SpoolDeal is checked against our own price history, so a discount only counts when the price is genuinely lower than it has been, not just lower than an inflated list price.
The best way to catch a Black Friday deal on a specific reel is a target price alert: set the price you want to pay and we email you when it gets there, during the event or after.
Common questions
When is Black Friday 2026?
Black Friday 2026 is on Friday, 27 November 2026, and Cyber Monday follows on Monday, 30 November 2026. Amazon UK usually starts its Black Friday deals a week or more before.
Are Black Friday filament deals really cheaper?
Often, but not always. Some listings raise their “was” price before the event. SpoolDeal compares every price with its own tracked history, so the discounts shown here are measured against what the reel actually sold for.
How do I get told when a filament drops in price on Black Friday?
Open the product on SpoolDeal and set a target price alert. It's free, and we email you as soon as its price reaches your target.
What makes a deal a gem?
A reel that's in stock and at least 25% below its usual price (the middle of the prices we recorded over the last 90 days), or at least 15% below it and at the lowest price we've ever tracked. Amazon's “was” price is never used.
How much did filament prices fall in Black Friday 2025?
During Black Friday 2025 (20 November – 1 December 2025), the typical filament listing we track fell 5% below its usual price at its lowest, and 57% of 1,628 listings were at least 5% below their usual price at some point. The figures come from our monthly filament price index.
How SpoolDeal checks prices
The same rules on every page, so a deal badge means the same thing everywhere.
Re-checked through the day
Every tracked listing on Amazon UK and Eryone UK is re-checked through the day, and the most-watched ones every two hours.
Measured against our own history
A deal only counts when the price is below what that reel has actually sold for over the last 90 days, not a seller's “was” price.
An email when it drops
Set a target price on any reel with a free account and we email you when it gets there.
