Telling my wife its only costing me 20 cents a shave. When i have enough soaps creams brushes and razors to last me the next 40 years lol
My best trick is having seperate accounts with the wife. No need to ask permission to get the stuff I want. Second best trick is work the lather. Lather matters a lot!
Not overdoing it. When I started I thought you had to do 3 passes to be shaving correctly, then I went down to 2 passes and my shaves are great.
Find the grain of you beard...it grows in different directions! This will help you go with the grain on the first pass, and make the overall shave experience go smoother.
