Tanga offers two Gillette MACH3 Turbo Cartridge 8-Packs (16 cartridges total) for $29.99. Coupon code "DEALNEWS" cuts them to $27.99. With $2.99 for shipping, that's $6 under the lowest total price we could find for this quantity elsewhere, although we saw 24 cartridges for a buck more in September. Each cartridge features triple anti-friction blades and lubricating strip. Note that these blades require a Gillette MACH3 razor to be used.
