Yeah, I've seen a few deals on the B&B forums, buy most are at least .30/CPB.
I can get other excellent blades for a lot less, and I'm not dead set on Feather blades. I've shaved with them twice so far and these are the "scary sharp" of DE blades.
I hear ya, I work a 7 and 7 and only shave when I'm working so that 100 pack will probably last me 10 years.
You have to try a feather blade in a slant, it probably the best combo out there.
