Judging by some of the smells that we encounter on a daily basis, some of us could use some incentive to wash up. Money Soap should motivate anyone to wash thoroughly, just to get to the cash in the center.
Those who use it often will be rewarded with either a $1, $5, $10, $20, or even a $50 bill once you get to the center. You will be both clean and just a tad wealthier.
It will cost you $10.98 from Amazon, so I hope you at least get the $10 bill.
