I use the generic CVS shave cream currently. I switched to the 5 blade razors last time I shopped, like nearly a year ago, and I'm still on the first box. Those things last an eternity. I tend to only shave once a week.
I used to use Lectric Shave but used regular 3 bladed razors because electric razors never seemed to get close enough. I also trim my beard with the same buzzer I shave my head with.
