This 16 Pack of Gillette Mach3 Razor Blade Refill Cartridges, listed at $79.99, is now $26.99 at Tanga. Shipping adds $1.99. That's $1.81 per refill, the best we could find by $0.30 per refill. For the best deal, buy three packs of 16, since shipping is $1.99 total for up to three packs. This would drop them to $1.73 per razor (or $82.96 shipped for 48 razors), the best by $0.39 apiece. Sales tax is not charged in most states.
