If you're trying to pick up your own copy of Diablo 3's soon-to-be-released Reaper of Souls expansion from Blizzard, you may have run head-first into a "500: Internal Server Error" message. The big downside to this error -- beyond your inability to buy the expansion -- is that though you don't get anything, you may still see the charge pending on your credit card. According to Blizzard support, because the charge didn't successfully go through, it should vanish within a few days. However, it doesn't leave us inclined to, as the error suggests, try again later.
Fortunately, Blizzard is on the case:
We're experiencing difficulties with pre-orders for Reaper of Souls. These issues will be resolved ASAP. Thanks very much for your patience!

Hopefully we'll see a resolution sooner rather than later -- with Reaper of Souls due out on the 25th, there's not much time left to buy for release-day gameplay. In the meantime, we're holding off on clicking "buy" until @BlizzardCS gives us the all clear.
