Look, box sales are a good way to let people buy boxes to save more tokens. However these sales appear out of nowhere. And you end up buying a gold box before its on sale

That said, there should be an in game reminder for the next item box sale or a reminder how frequent they are

It comes at the end of the weekend usually fridays sometimes if lucky, monday or on special occasions random 30% sales, just look at the calender.

Well, 2 sales came up unexpectedly on silver and gold packs as 15% sale. Plus a 25% sale came out last week on one of the weekdays toward the weekends. So they usually come out when nobody expects it
