Discounts ... what discounts are there?

I don't really understand the Black Friday discounts.

There are offers at 90% discount. I wait patiently for the time to come ... I click on BUY NOW ... and they are 70%

????

Let's see if someone can clarify it, thanks.

 

Here is how it works: https://blog.unity.com/games/find-your-next-asset-store-favorite-this-black-friday and it works this way. I bought more than one asset on 90%. I'm lucky.

 

Ok. Thanks.
