Yesterday, Oculus Rift headsets around the world stopped working due to a widespread and serious technical issue. Today, Oculus owned up to the issue and announced what it is doing to make it up to affected customers. If you experienced the issue--which rendered the VR headset basically useless--Oculus is giving you $15 in store credit.

"We're sorry for yesterday and want to help make this right. Thanks again for your patience," Oculus said.
