If you don't buy it now you will regret it later, as someone who's seen both times it's been sold I can easily say it's worth it and it's also way way way overrated. I didn't buy it the first time and I won't be buying it this time but I will pass on some sage wisdom. Run your weekly heroic on the highest lvl you can with as many characters available to get the coins or open the two small chests in PoE. Those are the best places to get the coins.
