El Black Friday does not start on the last Friday of November. Marketing campaigns usually start weeks earlier, and online stores already show early deals: “pre-Black Friday,” “exclusive prices,” “Black Week,” and more.
But… do prices really drop that day, or does it just seem that way?
If you want to know for sure, we suggest tracking online promotions by certifying the prices and offers of products with SaveTheProof. This way you can check which online stores genuinely lower prices and which ones “dress up” them.
Why start price tracking before Black Friday?
Every year, the Consumers and Users Organization (OCU) warns that many stores inflate prices before Black Friday to simulate big discounts.
With the digital certification of SaveTheProof, you can get ahead, and:

How to properly track prices with SaveTheProof
Here is a simple Tracking Plan to arrive prepared for Black Friday:
1️⃣ Make a list of URLs of your target products: technology, fashion, travel, or any category that interests you.
2️⃣ Start certifying prices one or two weeks in advance:
- Log in to SaveTheProof.com
- Choose the option Web Browsing Session, enter the URLs you have listed, and take visible area or full-page screenshots of the product price(s) and published purchase conditions. You have 50 captures per browsing session, which will be part of the certificate.
- The certificate will be saved in your SaveTheProof account, with date, time, and URL.
3️⃣ Repeat the process every few days: this way you can create a small “timeline” of prices.
4️⃣ On Black Friday, certify again and compare the prices with your previous certificates.
