cheaper source For future group buys, this place is cheaper and has free shipping. Not sure on if it's legitimate or not, worth a look http://www.opticsplanet.net/american-safety-razor-razor-blades-american-safety-razor-62-0165.html
Looks like that is the price for 100, rather than 200, so that makes it significantly more expensive.
i used to buy mine from this seller. looks like ill have to find a new source. he had 400 for the price of 200@ pella when i bought them.
