Back around 1990 a Roses store was going out of business and had reduced prices weekly. When it reached 70% off I went in the store and they had practically nothing worth buying.
I did happen to notice they had Gillette Sensor razors with I think 5 blades. They also had a coupon on them which made them free. I bought 3 sets then used the coupons over and over again until I had bought them all.
I have not bought a razor blade since and still have a bunch.
A few months ago I was in Wal-Mart and noticed they had Gillette Fusion 3 at $11 for a pack of 15 blades marked down. That did not seem all that cheap until I noticed the original price was around $35.
I had maybe two dozen Sensor handles I thought the blades would fit so I got a pack.
They did not fit and I had to go back and buy a razor along with a couple of blades.
I am now set with Gillette Fusion and Sensor razors for the rest of my life.
#20 I use the Fusion blades. They last 1 month before I replace them. I clean them good and dry the blade. So my cost is about $3 a month.
Gillette Fusion 12 blades at $34

You can save more and get a really close shave with double edge razor blades but you will have to be very careful or your shave will be too close!
You can just stop shaving like these guys.
