Prime Big Deal Days runs Tuesday, October 6 and Wednesday, October 7. Target and Walmart are running their own sales the same week. You will see a lot of red price tags.
Some of them are real savings. Many are not new lows at all.
This guide shows you how to tell the difference in about five minutes, so you buy with confidence instead of guessing.
What the numbers say
Visualping, a company that monitors web pages, studied about 2,500 Amazon products around this summer's Prime Day (May 22 to June 23, 2026). Of the products whose price changed:
- 12.5 percent hit a genuine new low.
- 44.7 percent simply matched a sale price they had already reached before.
- 42.8 percent were still higher than an earlier low.
In other words, close to nine in ten price changes were not the best price that product had seen. That does not make them bad prices. It means the sale badge alone does not tell you much.
What makes a discount honest
The Federal Trade Commission has a plain test for "was" prices. A former price is fair to compare against when it is "the actual, bona fide price at which the article was offered to the public on a regular basis for a reasonably substantial period of time."
A discount is dressed up when the "was" price was raised for a short time so the sale could look bigger.
So the question is never "how big is the percentage?" It is "what did this usually sell for?"
The five-minute check
1. Ignore the percentage. Look at the price. "55% off" means nothing until you know what it is 55 percent off. Write down the price you would actually pay, including shipping.
2. Find the usual price. Amazon now shows a Price History view on many product pages, with up to 365 days of prices. Look at where the price sat most of the time, not at the highest point on the chart.
3. Compare against the usual price, not the "was" price. If the sale price is clearly below where it usually sits, that is a real saving. If it matches a price you can see it hit last month, it is a fair price, just not a special one.
4. Check one other store. The same item is often on sale somewhere else this week. Target Circle Deal Days runs October 6 and 7, and Walmart Deal Days runs October 5 to 11. A minute of comparing can save more than the badge promises, and Sinclair can compare stores for you.
5. Decide if you need it now. If it is a gift, or something you already planned to buy, a fair price this week is a fine reason to buy. If it is an impulse, a fake discount is a good reason to wait. Black Friday and Cyber Monday are only weeks away.
A real deal versus a dressed-up one
Here is the difference in practice.
A real deal: a coffee maker that usually sells for one price most of the year drops well below it for two days. The "was" price matches what you saw it selling for in August.
A dressed-up deal: a coffee maker shows "was" at a price it only held for a week in September, then drops back to its normal price with a big red badge. Nothing really changed except the label.
Both carry the same badge. Only one saves you money.
Three shortcuts that help
- Lightning deals and limited-time drops are built to make you hurry. Take the five minutes anyway. A real deal is still a real deal after you check it.
- Bundles and multipacks can hide the unit price. Divide the price by the number of items and compare that.
- Store brands and look-alike listings often sit next to name brands with similar photos. Check the brand name and the seller before you add to cart.
Let Sinclair check it for you
Doing this by hand works. It also takes time you might rather spend elsewhere.
Sinclair, the free AI shopping companion from True Finds, does the checking for you. Paste a product link or its name at truefinds.ai, and Sinclair tells you plainly whether the discount looks real, based on the price history he keeps. If you shop in Chrome, the free True Finds extension can check the page you are on with one click.
A fake discount is not the same as a bad price. If you need it, that is still a fine reason to buy. You will just know what you are getting.
Quick checklist
- Look at the price you will pay, not the percentage.
- Find the usual price over the past few months.
- Compare the sale price to the usual price.
- Check one other store.
- Buy now if you need it; wait if it is an impulse.
