Shaving Supplies

For the cream, all you who use a razor and shaving, this question is for you!

I wonder: 1) how long a can of shaving cream last and 2) how many times did you replace your razor?

One can lasts me over a year.

I found shaving with baby oil gives a close, smooth shave and my razor blades last longer - because the shaving cream soap will damage the blades much faster. I leave with the shaving cream 10 years ago after trying the Baby Oil recommended a friend.
