First off, congratulations on that INCREDIBLE find. Now, second point, and I am sure everyone has tips and secrets...How do you find these deals?!?!?! Everytime I shop eBay for NOS razors, it's seems like 90% are all being sold by one seller out of Japan? And while some of their prices seem fair, nothing is a crazy value....
All I will say, hint hint, is it's all a matter of which eBay you're searching....
