Learn how to spot a real Black Friday deal using 90-day price history. Debunking myths about inflated list prices and the Omnibus Directive.
Black Friday is the time of year when everyone hunts for a true bargain. But are those huge discounts real? The truth is many brands raise prices before the sale week, then lower them to make savings look bigger than they are. In this article, we dissect real vs fake Black Friday deals using the 90-day price history as a "truth meter." You'll learn how inflated list prices work, what the Omnibus Directive says, and how Glitchoo helps you avoid traps.
How inflated list prices work on Black Friday
The mechanism is simple: a product sells at a normal price, then in the days or weeks before Black Friday, the price is artificially hiked (maybe by 40-50%). When Black Friday arrives, that inflated price is "struck through" and replaced with an apparent 30-40% discount, but the final price is close to the original.
Concrete example
Imagine a TV that went from $599 to $799 two weeks before Black Friday, then discounted to $599 with a "-25%" tag. If the price history shows it was $599 for months, the discount is fake: you're paying the same price as always.
The role of Glitchoo's 90-day price history
Glitchoo monitors product prices on Amazon for 90 days, comparing each deal against historical data. Our Trust Score assigns a reliability rating to the offer, and the -X% badge appears only when the discount is real versus the historical price, never by aggregating coupons.
Table: Real vs fake discount
| Product | Historical price (60 days) | Pre-Black Friday price | Black Friday price | Real discount | Glitchoo verdict | |----------|----------------------|------------------------|---------------------|--------------|-------------------| | 55" TV | $549 | $749 | $599 | -9% | Fake: cosmetic discount | | Bluetooth headphones | $39 | $39 | $29 | -26% | Real: constant history | | Smartwatch | $89 | $89 | $69 | -22% | Real: stable history |
Tip: always check the price history before buying. On verified deals you can see the Trust Score of each product.
Omnibus Directive: what changes (and what doesn't) for discounts
Since 2023, the EU's Omnibus Directive requires sellers to show the lowest price applied in the 30 days before the discount. It seems a win for consumers, but there are loopholes:
- Flexible reference price: retailers can use the lowest price without previous discounts, but if they raise the price for 30 days prior, the discount appears on a higher value.
- Exemptions: perishable goods, brand-new products, or those sold by third parties may be excluded.
How to use the directive to your advantage
- Always check the date of the last low price: on Amazon, you often find it on the product page.
- Use our price history: Glitchoo analyzes 90 days, not just 30, and shows if the increase happened before the protected period.
- Beware of discounts over 70-80%: they often hide an inflated list price or an aggregated coupon.
Real deal today: the example women's smartwatch with -80% off historical price is highlighted below. But always verify on Amazon because prices change constantly.
Most common Black Friday traps (and how to avoid them)
Here's what they want you to believe:
- "Up to 70% off" – the word "up to" is key: only a few products get that discount, most have minimal reductions.
- "List price" – manufacturers often inflate the list price to make the discount seem larger.
- Aggregated coupons – many sites sum coupons to the struck-through price to show a fake discount. We separate it.
Danger list
- Pre-event price increases: products that rise in price 2-3 weeks before.
- Fake "lowest prices of the year": sometimes history shows the price was lower months earlier.
- Light versions: models that look identical but have lower specs (e.g., less memory) sold at a seemingly discounted price.
To avoid all this, check daily the price errors section of Glitchoo, where we highlight deals with high Trust Score.
How to verify a discount in 3 steps
- Copy the product title and paste it into Glitchoo's search bar.
- Check the price history: you'll see the chart of the last 90 days and the real discount percentage.
- Read the Trust Score: if it's above 80, the deal is solid. If below, it might be a rip-off.
Attention: prices change hourly, even due to temporary glitches. If a deal has -84% like the featured laptop, it might be a price error: Amazon can cancel it. Don't force the purchase, don't try to exploit bugs, but if the price is real and history confirms, it could be a great chance.
FAQ
Is the struck-through price on Amazon always the lowest in 30 days?
No. The Omnibus Directive requires showing the lowest price in the 30 days before the discount, but it doesn't ban later increases for 30 days. In practice, if a product costs $50 and is raised to $80 for 30 days, then discounted to $60, the discount is on $80, not the real $50.
How do I know if a coupon is included in the discount?
On Glitchoo we always separate the discount percentage from the coupon. If you see a "-50%" badge but it includes a 20% coupon, the real discount is 30%. Never trust only the struck-through price.
Can a price error be honored by Amazon?
Amazon can cancel the order if it detects a price error, according to its terms. You cannot force the company to sell at a wrong price. If history shows an anomalous price, it might be a glitch: act fast, but without expectations.
Which products are most likely to have fake discounts?
Brand-name electronics, smartwatches, headphones, and fashion items. Categories with higher margins are more exposed to inflated prices. Always check the model's release date: if it's old, the discount might be real to clear stock.
Is my 30% discount real if history shows a lower price?
No. If the product was sold at $100, then $150 (increase), and now discounted to $120 with "-20%", you're paying more than real. Only if the historical price is constant or falling is the discount genuine.
Conclusion
Black Friday can still deliver real bargains, but you need to be armed with data. The 90-day price history is your best weapon to expose inflated prices. On Glitchoo, each deal is analyzed with our Trust Score, and the -X% badge is applied only when the discount is real, separated from coupons. Don't be dazzled by signs: always check verified deals and if you find a price error, act fast in the dedicated section. Remember: prices change daily, so monitor constantly to not miss true bargains.
