Hey there, bald brothers

I was wondering....
Where you get your blades from?
How expense are those blades?
How many of those you get of one shot?
How many times (shave(s) ) you use a blade?
What blade are you using?
What do you do when you run out of blades?
I'mma response to all above:D
I get the blades from random stores (where I can find some) ( I only buy the "Reserve" (the blade itself, you sure know what I mean).
I pay $1.23/blade.
I usually buy 2,3,5 ... today I've bought 7, so I'll be careless for X-mas.
I shave maximum 4 times with the same blade.
I use Gillette Blue 3
I usually get to the store in my village (they have some sort of Gillette Blue 3, but it's diffrent, I can only use it for a shave).
Thanks in advance for your time
