Came across the ebay listing where price was inflated during blackfriday sale.
Price of product was $479 and further 20% discount of blackfriday effective price should be $479-81.80 = 397.2
Later the base price was inflated to $529-$93.80=435.2
The same has been done for another model of the electric scooter by the same seller.
Have reported to eBay and see below screenshot
