trying to find old fashioned single blades seems to have gone the way of the buggy whip. Used to get them ar Walmart every time, but they then went missing. Asked the pharmacist where they went to and he advised that the store no longer handles them since they are used to cut drugs. Sheesh!
Amazon is your friend for DE blades, shaving soap, razors.
I left the $5 cartridge game 5 years ago and never looked back.
