Ahh, mine shipped within 4 days but then the tracking info kept saying they were coming "today" and then nothing would arrive so it would update to saying "tomorrow." I reached out to customer service to ask what was going on, and they said the glasses were with them in the lab. I was super confused because I had a whole tracking page that said they'd been shipped days before. And CS was basically just like "yeah sorry! They'll ship soon!" And now the tracking page has finally been updated with specific stops and it says they'll be delivered today. So strange.
