Not sure which one you are talking about. If you are talking about the 2 days jewel package. It's pretty decent. It had been a long time since I saw it, not sure if they ever change it. Correct me if I'm mistaken, the package gives around 4k jewels, a few magic papers, a bomb and a .
There are package promotions from time to time. That one have 3 different packages, can't remember much but is pretty good if you are a big spender in the game.
Other than those mentioned, there are also package when you reach certain lv. Can't remember at what lv. If I'm not mistaken, it's 50, 80 and 100.
If you are considering buying those packages, focus on the cost and how much jewels they give, don't look at the sweeteners(those extra items you get).
