Personally, I used to buy new products on the weekly and several during sales. Always looking at my Favorites to see if something is on sale and maybe finally decide to get it [that push over the line I needed to convince myself!]. Now, you trog through AI created content [labeled or not -we can all tell AI generated for the most part. Esp 2d.]
I had no idea about the sale mentioned right now because I don’t go to FAB’s market place as often as I did Epic. IT’s too … cumbersome. And the Launcher? Crashes everytime I go into the vault Library, so don’t really look at it much either. And Favorites? Non-existent.
I do hope Epic/FAB dev’s do fix this up but UEFN is far more of a priority and AI content is very used, and they clearly don’t care about any legal ramifications or worries. They just wanna play fortnite. 
We’ll see!
