Before all, I exported the database with the prices of Black November, Blackfriday 2022 and Christmas sales. There's really fishy prices like the product with the id of 6378fc29f2a8d33070b07298. As we can see there is a price boost in Black November and there is applied the discount that goes back to the normal price.
| Sales | Original Price € | Discount Price € |
|---|---|---|
| Black November | 279.9 | 219.9 |
| Black Friday | 279.9 | ---- |
| Christmas | 219.9 | ---- |
There's a lot more products with this fishy price oscillation! You can check the database file in the src/db folder.
