When 'Sale Price' Is a Lie: Reading Through Inflated Discounts
The pattern
A retailer raises the listed price of an item from $40 to $100 in late October. On Black Friday, they "discount" it back to $40 — labeled "60% off!"
The customer believes they got an enormous deal. The retailer paid for nothing. This pattern, called "phantom markdowns" or "anchor inflation," is the most common form of fake discount in 2026.
It's also the easiest to detect — if you know to look.
Tool 1: built-in price history (CamelCamelCamel)
For Amazon, CamelCamelCamel charts the price of any product over the past year. Open the product page, paste the URL into the site, see the actual price history.
Most "Lightning Deal" prices match or barely undercut the previous month's regular price. Genuine deals — where today's price is meaningfully below the trailing 90-day median — are rare and worth grabbing immediately.
Tool 2: built-in price history (Keepa)
Keepa is a browser extension that overlays a price-history chart directly on Amazon product pages. You don't have to leave the page or copy the URL. Install once, see the chart on every product.
Same logic: if today's price is at the bottom of the 90-day band, real deal. If it's mid-band, fake markdown.
Tool 3: PriceSpy / Google Shopping for non-Amazon
For retailers other than Amazon, Google Shopping shows the same product across all major sellers. If Macy's is selling something for $80 "marked down from $200" but Bloomingdale's, Nordstrom Rack, and Saks Off Fifth all sell the same SKU for $75-85 — the $200 anchor is fictional.
Search Google Shopping with the brand + product name + size. The price floor across all sellers is the real market price.
The 30-second mental check
When you see "60% off" or similar:
1. What was this product's price 6 months ago? (If you don't know, use a price-history tool.) 2. Is today's price meaningfully lower than that, or about the same? 3. If the same — it's a phantom markdown. Skip. 4. If meaningfully lower — actual deal. Compare to alternatives, then consider.
This check takes 30 seconds. It cuts your annual overspending on fake "deals" by hundreds of dollars.
Tell-tale signs of a phantom markdown
You can often spot the pattern without a tool:
- The item is a private-label brand only sold by one retailer. (No competitor exists, so no one can verify the original price.) - The "MSRP" sticker is suspiciously round (e.g., $99.99 marked down from exactly $200.00). - The "regular price" was set in the past 30 days. (Real regular prices have been stable for 90+ days.) - The discount is on a product that wasn't selling well at the listed price. (Why would a hot-seller need a 60% discount?)
If you see two or three of these on a single listing, it's probably phantom.
Real deals do exist
Genuine markdowns are seasonal and category-specific:
- End-of-season clothing: 50-70% off real prices. Real deal. - Electronics on Black Friday: 15-30% off the trailing 90-day median. Real deal. - Open-box appliances: 20-40% off, with full warranty. Real deal. - Auto-renewing software at first-year promo rate: real, but watch the renewal price.
The real-deal categories share a feature: there's a structural reason the price had to drop (seasonal cycle, new model release, refurb path, customer-acquisition subsidy). When the discount has no structural reason — when the item is a private-label perennial — be suspicious.
The 24-hour rule
When you see a "deal," wait 24 hours before buying.
- If it's a real deal in a stable category, the price will be roughly the same tomorrow. You can come back. - If it's an FOMO-driven phantom markdown, you'll either find the same listing at the same price tomorrow (proof it was fake), or the price will reset to the "real" level (which means today's price was a momentary inventory dump and you missed it — but you've avoided the overpriced anchor trick).
The exception is genuine doorbusters during major sale events (Black Friday morning, etc.) where stock genuinely runs out. For those, set up the alert in advance and click immediately when the door opens.
The bottom line
Discount percentages are marketing language. The actual price is the only number that matters. Train yourself to ignore "% off" in headlines and look at the absolute price next to the median market price for the same product.
A $40 item is a deal if the going market rate is $50. A $40 item marked "60% off $100" is the same $40 — and the only thing the markdown sticker proves is that the retailer thinks you don't know better.
Now you do.
