I'd pay $50 for a gallon of Dr. Bronner's 18-in-1 Peppermint Castile Liquid Soap.

You can easily resell it on the street in smaller containers, and make a big profit if you DILUTE! DILUTE! OK! [1] ALL-ONE-GOD-FAITH! [2]

Not quite $50 for a gallon, but just about there with free shipping:

  Dr. Bronner's Fair Trade & Organic Castile Liquid Soap   
  (Peppermint, 1 Gallon) $57.59 Prime

I love the soap! It's worth the few extra dollars to know you're getting the pure stuff. You have to be careful about what you buy off the street in gallon jugs. [1]
