Does that "sale" price hold up? Check it

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 "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.
🚨 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
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
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
- Install Zroppix free from the Chrome Web Store
- Open any Amazon product with a sale badge
- Click the Zroppix icon in your toolbar
- Check the verdict: BUY means the sale is genuine, WAIT means it is not
- 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
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.
