While those cartridge blades are taking a toll your wallet at $2-4 a piece, DE blades are much cheaper. Example? You got it!
Gillette Proglide replacement blades - $3-4 a piece
Schick Hydro replacement blades - $2-3 a piece
Derby DE blades - $0.30 – 0.35 a piece
Red Personna DE blades - $0.35 – 0.40 a piece
Feather DE blades - $0.40 – 0.45 a piece
You can’t argue with that.
