For everyone in the EU currently being spammed with black friday sales:
Check if they hiked the price to fake the sale
If they did, they're violating an EU mandate that started this year, that the "before price" HAS to be the lowest of the last 30 days. Fines can go up into the millions, so you really don't want to mess this up :>
Feel free to send them a gentle reminder if they do. I have zero sympathy for the practice or the companies doing it. Stop leaning on psychological warfare for sales
