hi.
I, as a daily shaver, I buy a blade ( gillette blue 3 ) which is $1.2, and I change it every 10 days. that makes about $4/month.
I also buy a gel every two months and a half, that makes another $5. souds cheap to me, comparing to the money you spend on the barberstop and/or shampoos and stuffs.
you don't really need an after shave, you can simply rinse with cold water to get rid of iritation, it works for me
