How we judge a price

Compared to what it usually costs

Every analysis rests on a dated chart, frozen the day it is published. You can check for yourself.

01

Twelve months of records

What the product actually cost over twelve months, not what it cost the week before the promotion

02

The hikes that come before

The increases that come before a discount

03

How often it's been beaten

How often the price has already been beaten, and by how much

What it changes for you

Know whether it's the right moment

No more guessing in front of a red tag

The verdict is plain: buy now, or wait, and why.

Stop overpaying for lack of information

A product advertised on sale at $30 that drops to $20 every couple of months shows it in its history. You just need to see it.

Stop watching prices yourself

Tell us the price that works for you. We watch, and let you know when it's reached.

What you can expect from us

Our commitments

We will also tell you when not to buy

If a price is merely fair, we say so. If the history shows it often falls lower, we tell you to wait. Our job is to save you money, not to make you click.

Our numbers come from real history

The usual price we show is computed from a year of readings. It does not depend on any seller's claim.

When we don't know, we say so
