Path of Exile but haven't converted that support into monetary form yet... well, that's fine, the game is free-to-play. But you're running out of time to take advantage of the Supporter Packs that were introduced as part of the game's launch. The packs will be officially discontinued very shortly, so if you haven't grabbed one yet, now's the time to do so.
The official announcement notes that you will be able to arrange a payment plan and/or upgrade your pack, but you need to set that in motion before the packs are gone for good, not after. So if you've been loving the game and want to buy a little power boost... do it now. You're running out of time.
