For me its not really the cost,it was just an idea and something I use.My good friend showed me imperial and I asked him about the shoe polish.A few days later he called me and said to run with it,that it was a really close mix to imperial wouldn't hurt a thing.I just like passing on the cost saving use of the mink oil.Plus I support the local with me buying it here at home.
I too have a large can of Minwax floor polish I think might work,but haven't tried it yet.Just might next time I need to FL a few cases.If it works I'll be good till the cows come home,and I have no cows that need to come home.
