Found some eBay sellers such as Loopmobile or Greengadget (Mobileworld) increase their prices during the black friday promotion.
For example, an Apple watch was listed at around $650 but when the 20%/22% promotion discount is out, they increase it to $850 which means you still get the same price as before or even higher (850 * 0.8 = 680).
A bit disappointed.
You only figured this out now?
Amazon and major physical retailers have been pulling this stunt for years.
