Each months, there's the refine rebates (best moment to use your refine runes), cave key exploration (use your cave key here), battle armor rebate (wait for it to use the threads) and there's also a new thing for the charms. I don't remember the name of the event, but when you used charms during that event, you get points and c*ed them to buy things.
There's also once a month, events to use you scrolls. so you can wait for it to use them :)

And i think it's all for the "saving and use at the right moment"
