On the range of razor blades, the Mach 3 or Mach3 razor stands in the middle.  It is the average man's primary shaver. Below the Mach 3 is the disposable razors or 2-blade razors.  And a step above is the Fusion razor with its big 5-blade cartridge.

But if you want a reliable smooth shave you can afford the Mach 3 from Gillette is for you.  Up until the Fusion Power razors came out, it was the top of the line when it came to razor blades.

If you've been using one for years, you know how much the replacement blades cost.  While they have come down lately they are still upwards to $2 and $3 a piece.  In a pack of 4 that will set you back about $12 each time.

Each blade will give you around 10 to 15 shaves depending on how often you shave and your hair type.  Considering you have to shave every day or every other day to keep away the 5 o clock shadow, that's about 15 to 35 blades you'll go through in a year.

Multiply that by $3 and you are spending around $45 to $105 a year just on razor blades.  Your mileage may vary.  You may use more or less razors depending on how often you shave and how often you want your girlfriend to kiss you.

It's easy to see why Gillette gives away the razor blade handles for almost nothing when they can get you on the hook for 50 to 100 bucks a year on buying new blades. 

There is a better way to buy them and save some time and money.  Start by checking out the deals below on Gillette Mach 3 razor blades.

I've bought 2 boxes of 40 blades on eBay in the past couple years and they have lasted me a couple years.  Each one cost around $40 to $45.  About a dollar a blade. 

This is what you can expect to pay when you buy them online.  You save over half off the retail prices which have their high markups. 

So you could have 1 to 2 years' worth of razor blade refills for around $40 and you save up to $65 off the normal retail cost. 

This is the smarter way to buy razor blades.  You avoid the middleman and buy your razors direct and save some money on things you have to buy anyways. 

If you need a new razor blade handle or if you want to try one of those sharpeners to keep your blades sharp you can buy one of those too.  It really pays to save money when you shop online for all your razor blade needs.

Buy them now while you are thinking about and don't wait until you run out and have to buy another 4 pack at the store for $12 a pop when you could have bought 12 razors online for the same price.

Your girlfriend will thank you when you always have a clean shaven face she loves to kiss.  Or she can thank me when you get to buy her a new pair of shoes with the money you saved.
