What do you do with saffron?

Incidentally, I posted something about saffron but am not sure those who likes saffron will visit the site posted in September
I buy saffron from Costco, still have more than half of the 14 gms of whole thread saffron for 89.99
Googling for spicy sardines on Ebay , I stumbled on to a seller who claims it was a gift(? Unbelievable as she has 8 of the 14 gms container left from Costco. She is asking 49.99 or best offer if anyone is interested)
I asked for the expiration date which I found at the back of mine. Seller has not answered. yet. It is a good buy if legitimate.
