Everything for smart shopping

Fake Discount Detector

Stores inflate prices before sales, then 'discount' them back. Lume saves the history of each product and shows real dynamics - you immediately see if the discount is real.

Telegram Alerts

The bot notifies you about products you track. The channel publishes a daily roundup of the best discounts from our database.
