Blizzak WS-50's, Not Available in USA??

I printed out the webpage for Blizzak WS-50s, took it to my mechanic and told him I wanted 225/60R15s. He called me today and said they're unavailable in this country. He told me he could still get them for at around $120 each - from who knows where? I'm just wondering if anyone else has ever heard of this?
BTW-I haven't told him to order them yet. Hopefully I'll make my decision by Monday, because snow should arrive shortly.
Also, does that price sound normal? (I have no idea)
Thanks again guys!
