Daily price history · AliExpress
A discount is only a discount if the price was ever higher.
I record AliExpress prices once a day and keep the history myself. A deal reaches the channel only when the current price sits meaningfully below the median of every observation I hold — never measured against the seller’s own “was” price.

Posts use affiliate links. AliExpress pays the commission — your price is unchanged.
01 — The problem
The “was” price is written by the seller.
On AliExpress the crossed-out price beside a listing is not a record of anything. It is a number the seller chooses, and it can stay there permanently. A product can advertise the same 60% off on every day of the year, which means the discount describes the label rather than the price.
So a percentage taken from that number tells you nothing about whether today is a good day to buy. The only way to answer that question is to have watched the price yourself, over time, and to compare against what it has actually been.
- The platform compares to
- A reference price supplied by the seller, which nobody verifies and which need never have been charged.
- This channel compares to
- The median of independently recorded daily observations, collected before the drop happened.
02 — The method
One rule, stated in advance.
The rule does not change per post, and it is the same rule whether or not a product is paying well that week.
-
Record
Every product on the watchlist has its price recorded once a day. The history is mine, stored independently of the platform.
-
Compare
When a price falls, it is measured against the median of every observation I hold for that product — a window that grows to a maximum of 60 days.
-
Qualify
The drop is published only if the current price sits meaningfully below that median. Beating the seller’s own “was” price counts for nothing.
-
Declare
Every post states the median it was measured against and how many days of observation that median is built from.
What disqualifies a drop
- A price that only beats the seller’s own reference price.
- A fall that sits inside the product’s ordinary price cycle.
- Any product I hold fewer than 14 days of observations for — it is not eligible, regardless of how large the fall looks.
03 — What a post contains
Every post carries its own evidence.
The point of publishing the median and the window alongside the price is that you can disagree with me. If the window is short, you can weigh the claim accordingly rather than take it on trust.
Product name
- Now
- $XX.XX
- Median
- $XX.XX
- ‹N› days observed
- Below median
- XX%
- the only number that decides
- Link
- affiliate link
- disclosed in every post
This is the format of a post, not a post. Nothing has been published yet, so there is no example to show you — the placeholders stay placeholders until there is real history behind them. Every post is published in both English and Hebrew.
04 — How this channel makes money
Affiliate links, and what they do not buy.
Posts link to AliExpress through an affiliate link. If you buy through it, AliExpress pays me a commission. You are not charged for it and the price you pay is the same as it would be without the link.
Commission rates play no part in what gets posted.
A product paying a high rate is held to exactly the same median rule as one paying nothing. If it does not clear the rule, it does not appear — and if the rule ever bends for a rate, the channel has no reason to exist.
I am not paid by any seller, I do not accept payment for placement, and no seller sees a post before it is published.
05 — What this is not
Things this channel will not do.
-
Not a coupon feed.
Codes and vouchers are not evidence that a price is low. They are not what is being measured here.
-
Not a dropshipping front.
I do not sell anything, hold stock, or have a relationship with any seller.
-
Not a firehose.
Most days nothing qualifies. A channel that posts every day is describing its schedule, not the market.
-
Not a mirror of platform sales.
Campaign banners and site-wide sale events are the platform’s marketing. Reposting them would be advertising, not measurement.
06 — Who runs this
Run by Shlomo. One person, one watchlist.
I built the collector because I wanted an answer the platform would not give me: is this actually cheap, or does it only look cheap today? The channel is that answer, published in the open.
The watchlist starts with electronics and accessories — the category where a permanent “sale” is most routine, and therefore where measuring properly changes the answer most often. It grows only as fast as I can genuinely track it, because a watchlist I cannot observe daily is not a watchlist.
Join the channel.
Joining now means you are there when the first verified drop is published — and you can hold me to the rule above when it is.
