You see it everywhere on Amazon. A red sale badge. A crossed-out price. "Was $79.99, now $59.99 — 25% off." It looks like a great deal. You feel the urgency. Your finger moves toward Add to Cart.

But before you click — ask yourself one question: was it actually cheaper before?

The answer, more than half the time, is no. The "was" price is a number that product may never have actually sold at. The discount percentage is calculated from a fictional reference price. And the sale badge is designed specifically to trigger your buying impulse — not to inform you of a genuine saving.

54%
of Amazon sale badges appear on products priced at or above their 90-day historical average — meaning the "sale" price offers no saving compared to what buyers paid in the past three months

🚨 The crossed-out "was" price on Amazon is called the "reference price." It is supposed to represent a recent selling price but is frequently set higher than the product ever actually sold — making the discount percentage misleading by design.

Real Sale vs Fake Sale — How To Tell the Difference

✅ Real Sale — Signs It Is Genuine

What a real Amazon deal looks like

  • Current price is below the 90-day average
  • Zroppix shows a BUY verdict
  • Price history shows a genuine drop
  • Less than 30% of buyers paid less than this
  • Name brand product with verifiable history
❌ Fake Sale — Red Flags

What a manufactured deal looks like

  • Current price is above the 90-day average
  • Zroppix shows a WAIT verdict
  • Price history shows a recent spike before the "sale"
  • More than 50% of buyers paid less than this
  • Unknown brand with a suspiciously high reference price

How To Check If an Amazon Sale Badge Is Real — 5 Seconds

  1. Install Zroppix free from the Chrome Web Store
  2. Open any Amazon product with a sale badge
  3. Click the Zroppix icon in your toolbar
  4. Check the verdict: BUY means the sale is genuine, WAIT means it is not
  5. Check the price history: is the current "sale" price actually below the 90-day average?

If Zroppix shows WAIT and the current price is above the 90-day average — the sale badge is meaningless. The product was cheaper before the badge appeared. You are not getting a deal.

What You See vs What the Data Shows

🚨 Sale Badge — But WAIT Verdict. It Was Cheaper Before.
Zroppix WAIT verdict on an Amazon product with a sale badge - current price is above 90-day average showing the sale is fake
Sale badge visible. But Zroppix says WAIT. Current price is above the 90-day average. The 90-day low was $9.89 vs the current "sale" price. This product was cheaper before the sale badge appeared.
✅ Genuine Deal — BUY Verdict, Price Below Historical Average
Zroppix BUY verdict confirming the current Amazon price is genuinely below the 90-day average
A genuine deal. Current price $42.74 is below the 90-day average of $47.58. This is not a manufactured discount — the price is actually lower than the historical norm. BUY with confidence.

The Amazon Reference Price Problem

Amazon allows third-party sellers to set their own reference prices — the crossed-out "was" figure. There are guidelines about how this price should be set, but enforcement is inconsistent and the guidelines themselves permit significant flexibility.

The result is a marketplace where products regularly show large percentage discounts from prices they never actually sold at. A product listed at $25 can show "was $50 — 50% off" even if it was $26 two weeks ago and $23 six weeks ago. The "50% off" figure is calculated from the $50 reference price, which no buyer ever paid.

The only protection against this is real price history data. Not the reference price. Not the crossed-out figure. The actual transaction prices from the past 90 days.

That is exactly what Zroppix shows you.

Frequently Asked Questions
How do I know if an Amazon sale badge is real?+
Check the 90-day price history. Install Zroppix free — open the product and click the icon. If the current sale price is at or below the 90-day average the sale is genuine. If the sale price is above the 90-day average the reference price was inflated and the sale is fake.
Are Amazon sale badges always accurate?+
No. Research shows 54% of Amazon sale badges appear on products priced at or above their 90-day historical average. The crossed-out "was" price is often calculated from a price the product never actually sold at.
What is the "was" price on Amazon?+
Amazon's "was" price is the reference price used to calculate the discount percentage. It is supposed to represent a recent selling price but research has documented many cases where it was higher than any price the product actually sold at in the prior 90 days.
