Meritline offers Replacement 3-Blade Razor Blade Cartridge 16-Pack
with free shipping
. (It's under "Buy More Save More".) That's $0.94 per cartridge, 6 cents under our per-cartridge price from three weeks ago, and $4 less than the lowest total price we could find for comparable blades in this quantity. (Note that these blades require a Gillette MACH3 razor to be used, not included.)
Expect these items to take two to three weeks to arrive.
