You can buy these blades on Amazon at a much cheaper price. Order a little more and get free shipping as well.

I wonder if anyone who has recently purchased blades from Amazon could post a pic or a description of the box they received their blades in. The one post about the Amazon blades in mmack66's link didn't match the pic in the sale. I know those who have ordered say it's not the same box as the pic, but I'm curious if they just sell what ever blades they got their hands on at the time. With all the reports of the Amazon blades rusting, and the ones I got even look and feel different, I don't know how anyone can still think they are the same blades.
