One, the quality of the saffron makes a big difference in price. Longer deeper red strands are much more expensive than shorter and more yellow strands. I suspect they are not using the most expensive saffron in their teas.

Two, there's a lot of markup purchasing saffron from most retailers, especially here in the US. You can get that amount of saffron for far less than $10,000 if you know someone who has a connect.

Three, as you said the majority of saffron production is from Iran. Some friends I know are getting their saffron from the UAE but I'm pretty sure its being re-exported from Iran.

Four, those videos are ultimately productions. If you compare the earlier videos to the later videos on some of that channel you can tell they've upgraded their digs. They might just be exaggerating for the camera.
