"Black Friday Big Spender Event"

Every single NX that you spend on Cash Shop items is redeemed in points. You can use those points to pick an item from the Black Friday CS shop. So basically, the items from the event shop are free. Pink Bean doesn't cost 50k NX, it is complimentary if you spend 50k NX worth of points.

While true, it's also a plantain move to stick items in there that many of us have been waiting months for.
They know people have been waiting for scrolls, and now people will spend more NX in order to get them. NX that they wouldn't have even needed to spend if they had put them on sale like normal.
