Product’s price history – how to check it?

Nowadays prices in e-commerce can change multiple times a day. This is due to brands’ promotional campaigns and changes based on different market conditions (dynamic pricing). Seasonal and occasional changes are other situations in which prices fluctuate – a good example of it is Black Friday. It’s counter-intuitive, we know, but even 60% of product prices go up during Black Friday – according to the research of British organisation Which.

That’s why it’s important to track prices from different perspectives:

  • e-store – to compare offered prices to the ones offered by competitors
  • manufacturers – to verify at what prices brand products are being sold and to check if there are no ongoing price wars
  • customers – to avoid being fooled by “fake promotions”

In this article, we will show you how to verify a product’s price history and compare prices between different sellers. Get to know how to check a product’s price history using Dealavo (a solution for shops and manufacturers) and on platforms such as Amazon, Ceneo, AliExpress and many more.

Price history – why is it important to know it?

For example, the same products may cost hundreds of dollars more just a few days later. With little effort you can conveniently check given product’s price history, thanks to which you can see:

  • in which months products are the most expensive
  • whether a specific product is really getting cheaper during the special offer period
