eBay is your friend. There are a few sellers from Bulgaria with high reputation (>99.7%) who can sell Polisilver Super Iridium in bulk (e.g. 1000 blades). Prices with delivery are better than anywhere else.
Also saw Personna blue med prep a few times there.
Didn't stop me from stocking up though LOLThere are no single evidences it's been discontinued except on one site. There was a thread on B&B forum about that. People think it's just a trick to attract sales.

I have about the same @SpeedyPC. I worked out that it is between 35 and 40 years worth of blades
I also bought from this guy without any issues.I bought mine from aggr-bg and haven't had any issues.
