Is That Black Friday Price Real? Check It in 3 Minutes
Short answer: Black Friday 2026 is November 27. An Oxylabs study of Black Friday 2024 found 60% of assessable products most likely had fake discounts. Check a 90-day price history on a tracker, compare the sale price with the lowest price in that window, and log prices weekly starting now.
A red tag is not evidence.

When is Black Friday 2026, and how long do you have to check prices?
Black Friday 2026 falls on November 27 and Cyber Monday on November 30, which gives shoppers about five weeks from October 21 to build a price baseline for anything on their list.
That gap is the whole advantage. A tag that says 40% off tells you nothing without the number it is measured from, and the only way to know that number is to have watched it.
How often is a Black Friday discount fake?
In an Oxylabs study of Black Friday 2024 that tracked 61,172 product URLs on two major US marketplaces from August 13 to November 29, 2024, 2,717 of the 4,529 products it could assess (60%) most likely had fake discounts.
Oxylabs counted a discount as fake when the advertised former price did not appear at least half the time in the 90 days before the sale, a test it based on the FTC’s “regular basis” standard and California’s 90-day rule. It also counted items that were “on sale” the entire period.
| Check (Oxylabs, Black Friday 2024) | Marketplace 1 | Marketplace 2 |
|---|---|---|
| Deal was lowest price of the prior week | 28% | 59% |
| Deal was lowest price of the prior month | 88% | 86% |
When I compared the two rows, I found that the month test looks reassuring while the week test does not. A price can be the lowest of the month and still be higher than seven days earlier.
The authors caution that results cannot be generalized to other countries, and that a 90-day yardstick may be too long for fast-moving online sellers. Read it as a warning, not a verdict on every store.
How do you check a price history in three minutes?
To check whether a Black Friday price is real, open the product’s price-history chart on a tracker such as Keepa or CamelCamelCamel and compare the sale price with the lowest price in the prior 30 and 90 days.
- Step 1: Find the product page and copy its ID or link into the tracker.
- Step 2: Read the chart for the last 90 days, not the 30-day default.
- Step 3: Mark the lowest price and the typical price. Ignore the “list price” line.
- Step 4: Look for an October spike that makes November look like a drop.
- Step 5: Set an alert at your target, then walk away.
| What the chart shows | What it means |
|---|---|
| Flat price, then a sudden jump, then a cut back to flat | Likely inflated reference; the deal is the old price |
| Sale price equals the lowest of the last 90 days | Genuine, if you need the item |
| Price already lower 30 days ago | Wait or buy the older price if it returns |
| Always “on sale” with no regular price | Treat the sale price as the real price |
Most people skip step two and regret it. A short window hides the spike.
What do the rules say about “was” prices in the US?
The FTC’s Guides Against Deceptive Pricing (16 CFR Part 233) say a former price used for comparison should be the price at which the product was actually and openly offered for a reasonably substantial period of time.
The guides are not a law that guarantees you a refund, and they do not give a day count. That is why independent price history matters more than the sticker.
The EU has a firmer rule: since 2022, retailers advertising a reduction must show the lowest price from the previous 30 days. That applies to EU retailers only, so US shoppers cannot count on it.
A Five-Week Plan Before November 27
Pick your top five purchases this week. Start a price log: tracker screenshot, date, price. Do it again every Sunday.
If you’ve ever bought a TV on the first day of a sale, you know the feeling of seeing it cheaper in December. The log is the cure.
| Week | Action |
|---|---|
| Oct 21–27 | Add five items to trackers; record today’s price |
| Oct 28–Nov 3 | Note any October spike or drop |
| Nov 4–17 | Record the two-week low and set alerts |
| Nov 18–26 | Check for early Black Friday cuts against your log |
| Nov 27–30 | Buy only if price is at or below your logged low |
I noticed that none of the guides I read give a number for how long to track. Four to five weeks is my own suggestion, chosen because it covers one full pre-sale price cycle.
Tips
- Look at 90 days of history, not the default 30.
- Set a price alert at your target instead of checking daily.
- Screenshot the chart before you buy so you can dispute a misleading claim.
Warnings
- A price tracker can miss third-party seller prices or coupons.
- Limited stock can mean a good price sells out; know your walk-away number first.
- Study results from 2024 US marketplaces do not prove any single 2026 deal is fake.
FAQ
When is Black Friday 2026?
Black Friday 2026 is Friday, November 27, and Cyber Monday is Monday, November 30.
How can I tell if a Black Friday discount is fake?
Compare the sale price with the product’s lowest price over the previous 90 days on a price tracker; if it was lower or equal recently, or the item has always been on sale, the discount is not what the tag implies.
Do US retailers have to show the lowest recent price?
No. The EU requires showing the lowest price from the previous 30 days, but in the US the FTC’s pricing guides only say a former price should have been openly offered for a reasonably substantial period.
