Would you buy a completely natural, fresh, handmade facial mask for $3?

Okay so my mum owns a beauty business and i'm helping her out with some new idea's. I am a big fan of lush cosmetics, but even oatifix (the Lush cosmetics fresh face mask) contains other non natural chemicals in it. I have made a fresh face mask out of pure honey, blended (practically to powder) oats, mineral water and natural vanilla essence and it worked brilliantly on my skin so I was thinking of giving my mum the idea for her business? Also all lush cosmetics have to be kept chilled as they add eggs and other dairy products that can go bad. All ingredients in this mask have a long shelf life. Whats your idea's? and Would you buy it for $3? Thanks for reading!
