I won those razor blades!

Wow ... 100 razor blades for my M3 Power Razor. I can't wait to get them (well, actually, I guess I can, as I have a few weeks' worth of blades already). Got them for about $1.30 / blade, which is better than the best price I was able to find on the web ($2.48 / blade). Anyone know of any other cheap sources? Although -- I won't be needing blades for quite some time (and by the time I do, Gillette will have a new "must have" razor out, I'm sure).
