Razor blades are ludicrously expensive, and if you're not buying your disposable razor blades from Amazon, you're probably paying too much. Amazon normally has refill cartridges at rock bottom prices, and the world's biggest store runs frequent coupons to make these deals even better. Today's Deal of the Day on Gillette products takes the bargains to a whole new level with a 25% discount that stacks with a $6 instant on-screen coupon.

If you shave with a Mach3, a Fusion, or a Venus, stock up on the cheap today. You won't regret getting 16 Mach3 Turbo blades plus an extra handle for just $17.99 or eight Venus Spa blades plus an extra handle for just $14.85. (To put that bargain in perspective, a pack of just 15 Mach3 Turbo blades is currently $27.93 on Walmart.com without the benefit of Prime shipping, while a six-pack of Venus Spa blades will set you back $20.99.)
