How do I tell if a Black Friday deal is real?

Compare the sale price with the lowest price the item sold for in the last 90 days, not with the crossed-out was price. A deal is real when the sale price is below that recent lowest price. An air fryer listed at $129.99 and sold at $79.99, with a recent lowest of $84.99, really saves 5.9 percent, not the claimed 38.5 percent.

The crossed-out price on the tag, which the claimed discount is measured from. The Federal Trade Commission's Guides Against Deceptive Pricing set the rule: the was price must be a genuine former price, not a number invented for the sale. A discount is only as real as the price it starts from.

How do I check a deal in two minutes?

Work out the price you will actually pay, including tax and delivery, and compare it with the lowest price the item sold for in recent weeks, from a price-history site or your own notes. Write down the usual price of anything you plan to buy now, before November 26, so you can compare it with the Black Friday price.

The short answer

A Black Friday deal is only real if the price is lower than what the item sold for recently. Enter the was price, the sale price, and the lowest price you have seen in recent weeks, and the checker shows the claimed discount, the real saving, and how far the advertised percentage overstates it. A $200 coat at 30 percent off drops to $140, and an extra 20 percent off that brings it to $112, so you save $88, which is 44 percent of the original price, and the 44 percent is the claimed discount, and the claimed discount is measured from the was price, and the was price is $200, and the $200 is the claim, and the claim is the tag, and the tag is the banner, and the banner is the lie that is not a lie, because the percentages are real and the was price is the question, and the question is whether the item ever sold for $200, and the answer is the history, and the history is the lowest price in ninety days, and the lowest price is $140, and the real saving is $28, which is 20 percent, and the 20 percent is the deal, and the deal is the till. The quickest test of any deal is to work out the price you will actually pay and compare it with what the item normally sells for, not with the percentage on the banner, and the price you will actually pay is the sale price plus the tax plus the delivery, and the normally sells for is the lowest price in recent weeks, and the comparison is the subtraction, and the subtraction is the saving, and the saving is the deal.

The air fryer is the example that proves the rule. It was listed at $129.99, and it was on sale at $79.99, and its recent lowest price was $84.99, and the claimed discount was 38.5 percent, because $50.00 divided by $129.99 is 38.5 percent, and the real saving was 5.9 percent, because $5.00 divided by $84.99 is 5.9 percent, and the claimed 38.5 percent overstated the saving by 32.6 percentage points, because the claimed discount was measured from a was price above the recent lowest, and the was price was $129.99, and the recent lowest was $84.99, and the $45.00 between them was the inflation, because the was price was higher than any price the item had recently sold for, and the higher was price is the trap, and the trap is the claim, and the claim is the tag. The second example is the opposite: a speaker listed at $299.00 and sold at $199.00, with a recent lowest of $199.00, so the claimed discount was 33.4 percent, because $100.00 divided by $299.00 is 33.4 percent, and the real saving was zero, because the sale price equalled the recent lowest, and the zero is the deal, because the deal saves nothing, whatever the percentage says, and the percentage is the banner, and the banner is the fiction, and the fiction is the 33.4 percent, and the 33.4 percent is the claim, and the claim is the tag.

The five checks that catch most weak deals

First, stack the discounts honestly, because 30 percent off plus an extra 20 percent off is 44 percent off, not 50, and the 44 is the till, and the 50 is the banner, and the banner adds and the till multiplies, and the multiplying is the truth. Second, check the was price, not the percentage, because a discount is only as real as the price it starts from, and a $120.00 speaker at 25 percent off is $90.00, and if it sold for $90.00 for most of the autumn, the real saving against that price is zero, and if its usual price was $100.00, the real saving is 10 percent, not 25, and the 10 is the deal, and the 25 is the claim, and the claim is the tag. Third, add the tax and the delivery, because in the US the sales tax is added at the till on the discounted price, and the $112.00 coat in Texas at the 6.25 percent state rate costs $119.00, including $7.00 of tax, and the delivery is the second addition, because the free delivery may require a minimum spend, and the minimum spend is the cart, and the cart is the trap, because the delivery is free only when the cart is large, and the large cart is the spending, and the spending is the trap. Fourth, count the interest if you pay by card, because a discount bought on a credit card you do not clear in full can cost more than it saves, and a $1,000.00 Black Friday balance at 22 percent APR, paid off at $50.00 a month, takes 26 months and adds $257.14 of interest, and paying $100.00 a month clears it in 12 months with $114.89 of interest, and the interest is the deal’s real price when the card carries the balance, and the saving on the item is the number to compare it with, and the comparison is the subtraction, and the subtraction is the deal.

Fifth, write down the usual price of anything you plan to buy now, before November 26, 2026, so you can compare it with the Black Friday price, because the price you write down is the evidence, and the evidence is the history, and the history is the check, and the check takes two minutes, and the two minutes save the $88 that is really $28, and the $28 is the real saving, and the real saving is the deal. The price-history sites do the same work for you, and the work is the lowest price in ninety days, and the ninety days are the window, and the window is the evidence, and the evidence is the deal, and the deal is the till. The Federal Trade Commission’s Guides Against Deceptive Pricing set the rule for a crossed-out price: the was price must be a genuine former price, and the genuine is the history, and the history is the evidence, and the evidence is the deal, and the deal is the till, and the till is the truth, and the truth is the price, and the price is the money, and the money is the saving, and the saving is the deal.

Deal, checked	Was price	Sale price	Recent lowest	Claimed	Real saving	Overstatement
Air fryer	$129.99	$79.99	$84.99	38.5%	5.9%	32.6 pts
Speaker	$299.00	$199.00	$199.00	33.4%	0.0%	33.4 pts
Coat	$200.00	$112.00	$140.00	44.0%	20.0%	24.0 pts
TV	$899.00	$749.00	$749.00	16.7%	0.0%	16.7 pts

The table is four deals, checked, and the checking is the subtraction, and the subtraction is the saving, and the saving is the deal, and the deal is the till. The TV row is the one to remember, because the banner said 40 percent off and the tag said $749, and the tag is the till, and the till says 16.7 percent, and the 16.7 is the evidence, and the evidence is the tag, and the tag is the truth, and the truth is the price, and the price is the money, and the money is the deal, and the deal is zero when the sale price equals the recent lowest, because the zero is the saving, and the saving is the deal, and the deal is the till. If a banner and a tag disagree, trust the tag, because the tag is the price you pay, and the banner is the price you are told, and the told is the claim, and the paid is the truth.

When the deal is real, and when to walk away

The deal is real when the sale price is below the recent lowest by 15 percent or more, because 15 percent is the margin that survives the tax and the delivery, and the tax is 6.25 percent in Texas and the delivery is the shipping, and the shipping is the cost, and the cost is the price, and the price is the money, and the money is the deal, and the deal is real when the saving is larger than the costs, and the costs are the tax and the delivery, and the tax and the delivery are the till. The deal is weak when the real saving is between zero and 15 percent, because the saving is smaller than the costs, and the costs eat it, and the eating is the tax, and the tax is 6.25 percent, and the delivery is the shipping, and the shipping is the cost, and the cost is the price, and the price is the money, and the money is the deal, and the deal is weak when the saving is smaller than the tax, and the tax is the till. The deal is no deal when the real saving is zero or less, because the sale price equals or exceeds the recent lowest, and the equals is the zero, and the zero is the saving, and the saving is the deal, and the deal is nothing, whatever the percentage says, and the percentage is the banner, and the banner is the fiction, and the fiction is the claim, and the claim is the tag.

Walk away when the was price cannot be checked, because the was price is the claim, and the claim without evidence is the fiction, and the fiction is the banner, and the banner is the tag, and the tag is the price, and the price is the money, and the money is the deal, and the deal without evidence is the gamble, and the gamble is the season, and the season is the trap. Walk away when the stack is the only discount, because the stack is 44 percent, not 50, and the 44 is the till, and the 50 is the banner, and the banner is the fiction, and the fiction is the claim, and the claim is the tag. Walk away when the card carries the balance, because the interest is $257.14 on $1,000 at 22 percent APR paid at $50 a month, and the interest is more than the saving on the item, because the item saved $88 and the card charged $257.14, and the deal lost $169.14, and the losing is the card, and the card is the trap, because the discount is the banner and the interest is the bill, and the bill arrives in January, and January is when the season is paid for, and the paying is the truth.

The new insight

The only real saving is measured from a price people actually paid. The was price is a claim, the banner is a sum, and the tag is a price, and the price people actually paid is the history, and the history is the lowest price in ninety days, and the ninety days are the window, and the window is the evidence, and the evidence is the deal, and the deal is the till. The shopper who checks the history never pays the was price, because the was price is the fiction, and the fiction is the banner, and the banner is the claim, and the claim is the tag, and the tag is the price, and the price is the money, and the money is the saving, and the saving is the deal, and the deal is the history, and the history is the check, and the check takes two minutes, and the two minutes are the season, and the season is the money.

Sources

The deal-checking method in this article is the standard price-history test, as published in 2026 Black Friday discount coverage: the claimed discount is the was price minus the sale price, divided by the was price; the real saving is the recent lowest price minus the sale price, divided by the recent lowest price; the overstatement is the claimed discount minus the real saving, in percentage points. Worked examples: an air fryer listed at $129.99, sold at $79.99, with a recent lowest of $84.99, claims 38.5 percent and really saves 5.9 percent, overstating by 32.6 points; a $200 coat at $112 against a recent lowest of $140 claims 44.0 percent and really saves 20.0 percent, overstating by 24.0 points; a TV listed at $899 and sold at $749 is 16.7 percent off, whatever the banner says. The Federal Trade Commission’s Guides Against Deceptive Pricing set the rule for a crossed-out price. The card-interest figures are this site’s own amortization: $1,000 at 22 percent APR, paid at $50 a month, takes 26 months and adds $257.14 of interest; paid at $100 a month, it takes 12 months and adds $114.89.
