Some time ago, I wrote about how I shave with a 2 blade razor and how unfortunately Gillette has basically stopped selling the line I use in the US. I was buying the blades off of Amazon. I finally gave up.
Now I just buy the disposable version from Target or Amazon. I don’t like using disposable razors, but they are about 95% as good as the replaceable blade version and about 50% of the cost. So it goes.
