Where Black Friday Comes From - The Friday the Books Turn Black
Black Friday is the day after Thanksgiving in the United States (the fourth Thursday of November). Retailers launch large-scale sales to mark the opening of the Christmas shopping season.
Several explanations exist for the "black" in the name, but the best known is that it marks the day retail ledgers move from red (loss) into black (profit). A large share of annual sales concentrates on this single day, enough for one day of trading to erase a year of losses.
In Japan, Amazon and Rakuten introduced the event around 2016, and it took hold quickly. It amounts to a new large-scale sale added to the annual calendar covered in the rules of sale timing.
Yet is the "steep discount" of Black Friday genuinely a good deal? Consumer agencies and research bodies in several countries have examined what sale prices actually look like. The findings are not necessarily welcome news for shoppers.
The Reality of Raising Prices Before Cutting Them
The most criticized practice on Black Friday is raising the price before the sale, then returning it to the original level during the sale and labeling it "X% off."
According to research by the UK consumer group Which?, the majority of Black Friday "sale items" had been available at the same price or lower at some other point during the year. In other words, they were not specially cheap - they sat within the normal range of price movement.
Isolated from everything else, the mechanism is simple. Raise the displayed "regular price" just before the sale, and the discount rate on the label grows even though the price actually charged never moved. What the shopper sees is the ratio labeled "X% off," and the product page reveals nothing about whether the reference price was genuinely in effect until the day before.
Like the shrinkflation described in the psychology of price hikes, this is a way of shrinking the real reduction in a form shoppers rarely notice. It calls for the habit of using the math of discounts to test whether the "original price" was ever reasonable.
How to Verify the "Original Price" - Look at Price History, Not the Discount Rate
Whether a displayed discount rate is reasonable cannot be judged without confirming the price it was measured against. That check is available to the shopper as well. Decide the order of the steps in advance and the time spent hesitating on sale day gets shorter.
The steps summarize the verification methods covered in this article. Whether price history is available at all varies by product and by how it is sold.
Use a price tracking tool. Browser extensions that display Amazon price movements (Keepa, camelcamelcamel) show the full price history at a glance. They let you judge from data whether the "Black Friday price" is truly the lowest.
As covered in the review economy, the sense of a bargain makes calm judgment harder during a sale. A price tracking tool is a powerful defense against being carried by emotion.
Which Products Are Genuine Deals and Which Are Not
Here is how to separate the products that genuinely get cheaper on Black Friday from the ones that only appear to.
Products that tend to be genuine deals. Previous-generation appliances (older models after a new release), Amazon devices (Echo, Fire TV, Kindle), games released more than six months ago, and bulk packs of household staples. These carry a strong element of inventory clearance, so the real reduction is large.
Products where the discount is often cosmetic. Fashion (where the "reference price" is easily set arbitrarily), unbranded appliances (where the original price itself is opaque), and "Black Friday exclusive models" (where no comparison exists, so the discount rate cannot be verified).
What divides the two is whether the reason for the reduction is clear. Older models and clearance stock come with an explanation for why the price falls. An exclusive model with no comparison offers neither a reason for the discount nor any external evidence that a discount happened.
"Today Only" Rushes the Decision - The Time Limit Is Part of the Design
The trouble with Black Friday is not confined to how prices are displayed. The fact that the window is bounded works to make shoppers skip the effort of checking price history.
Countdown timers, remaining stock counters, the framing of a "flash sale." All of them are built to create the feeling that a chance will be lost unless you decide right now. As covered in the psychology of limited editions, when options are visibly shrinking, people work to avoid missing out rather than to weigh the price itself.
The problem in that state is that the verification steps above start to look like a chore. Opening the price history and comparing it with the record low takes under a minute, but with a countdown running, that minute feels expensive.
The fix is simple: keep the checking off sale day. If the candidates are already chosen, the price history can be reviewed before the sale opens. Reduce the task on the day to confirming that the final price fits the budget, and the quality of the decision holds up even under pressure.
Five Rules for Shopping Smart on Black Friday
These are the rules for making good use of Black Friday.
- Build the shopping list in advance. List what you genuinely need before the sale starts, and buy nothing on the day that is not on the list. This is the most effective counter to the psychology of limited editions.
- Check the lowest past price in a tracking tool. Confirm whether the Black Friday price falls below the lowest price on record. If it does not, there is no need to hurry.
- Judge by the final price, not the "X% off." Even at 70% off, skip it when the final price exceeds your budget. As explained in the math of discounts, judge by the amount you pay rather than the discount rate.
- Compare effective prices including point rewards. Check the same product on Amazon, Rakuten, and Yahoo! Shopping, and decide on the effective price with point economies factored in.
- Read the return policy. As covered in the psychology of return policies, a returnable product leaves the option of buying now and deciding once the excitement fades. Return conditions on sale items sometimes differ from the usual ones, so check beforehand.
Choosing Not to Buy That Day - Measuring the Distance to the Next Chance
When a product fails the conditions above, the remaining choice is not "never buy it" but "wait for the next chance." The two look similar, yet the reasoning differs.
Black Friday is one sale among many across the year. As covered in the rules of sale timing, each product category has periods when prices tend to fall, and fiscal year ends and new model launches are built into that cycle. When you roughly know when the same price level returns, passing today costs little.
Purchases with an unreadable next chance are the harder call. Discontinued model numbers and clearance stock that ends when it runs out do not get cheaper with waiting - only the options disappear. Sorting items into what can wait and what cannot reduces the hesitation on the day.
And the effect of a purchase never made does not show up in any number. What pushes annual spending down is not the purchases with the largest discount rates but the number of times you stopped a purchase that was never on the list. As touched on in the psychology of return policies, even when returns provide an exit, passing is often cheaper once the effort of the process is counted in.
Frequently Asked Questions
Can I take a Black Friday "X% off" label at face value?
The discount rate alone is not enough to judge. The rate is a ratio against an "original price," and the product page does not reveal whether that price was actually in effect until the day before. Research by the UK consumer group Which? reported that the majority of sale items had been available at the same price or lower at some other point during the year.
Which products are most likely to be genuinely cheaper?
Products where the reason for the reduction is clear. Previous-generation appliances after a new model launch, Amazon devices, games released some time ago, and bulk packs of household staples carry a strong element of inventory clearance, so the real reduction tends to be large. Fashion, where the "reference price" is easily set arbitrarily, and sale-exclusive models with no comparison make the discount rate itself impossible to verify.
What should I look at in a price tracking tool?
Two things: the lowest price on record, and how the price moved just before the sale. Check whether the current price falls below the record low, and also whether the displayed "regular price" was lifted ahead of the sale. Meet both and the reduction is real; miss either and there is no need to hurry.
How should I decide when I am unsure about buying?
Framing it as "can this wait for the next chance" rather than "should I skip it" makes the call easier. Because each category has periods when prices fall, passing costs nothing when the same level is expected to return. Discontinued products and clearance stock will not fall further, so sorting items into what can wait and what cannot ahead of time is the useful step.
