About Pickoryx

Pickoryx watches prices on Amazon.comand surfaces the drops that are actually worth your attention. A crossed-out “list price” is easy to inflate, so we do not take one at face value.

How we decide something is a deal

Every product is measured against two anchors, and the better-founded one wins:

• List price. If the product genuinely carries a list price above what it costs today, the discount is measured against that — the familiar percentage.
• Its own typical price. Most products have no meaningful list price. For those we use the duration-weighted 25th percentile of the last 90 days of that product’s own price — in plain English, “what this thing normally costs.” A seller cannot inflate that number. To count as a deal on this anchor, the price has to be at least 10% below normal.

There is also a veto: if the current price is more than 10% abovethe product’s own normal price, it does not appear as a deal no matter what the list price claims. That single rule is what keeps a permanently “40% off” product out of the feed.

Typical price is not the all-time low

They are two different numbers and we show both. Typical price is the normal price band. Lowest we’ve tracked is the cheapest price we have actually observed since we started watching the product, with the date it happened.

Where the data comes from

Product data comes from the Amazon.com Associates catalogue APIs. Prices are read on a schedule — products that move often are checked more often — and each product page shows the exact moment of the reading. Nothing here is a live price. By the time you reach Amazon.com, the price may have changed; the price shown there at checkout is the one that applies.

What we deliberately do not show

• Star ratings and review counts. Displaying and caching that data is constrained by the Amazon.com Associates operating agreement, so we leave it out rather than guess at what is permitted.
• Sponsored placements. No brand can pay to appear here or to rank higher. Ordering comes from the discount maths and nothing else.

How we make money

As an Amazon Associate we earn from qualifying purchases. When you follow a link from here and buy something, Amazon.com may pay us a commission at no extra cost to you. It does not change what we show you or the order we show it in. The full statement is on the affiliate disclosure page.

Found something wrong?

Wrong price, dead link, product that should not be here — the report button on any product page goes straight to the person who can fix it.
