The trick is to never go in with the premise of saving $
My wife's quite happy, fortunately my nibblings of AD tend to be towards creams and soaps, both of which are fairly inexpensive, and she much prefers the scent over the canned goop. She's also happy that I enjoy shaving now rather than moaning about it.
Now that I think about it, after her grandma died she was going through some of her stuff and found her granddad's Gillette Tech. She's pleased that I've had it restored (thanks Onotoman!) and am using it rather than it just getting thrown out, or being left in a box and forgotten.
