Great story. Just started wet shaving myself and i actually felt the same way as your wife while reading some people's routines. I personally only use a shower, lather, and after shave with no other prep or after products. However, everyone is different, some people's skin needs more treatment to receive a smooth shave and there's nothing wrong with that. My skin happens to be very tough and not sensitive at all. However, to your wife's point maybe using less products could have just the same affect and save money on that long run. I say give it a shot, but do what's best for you.
