I had to chuckle at this, my little 9 year old grand-daughter sold ice cold water for .50 cents, when there was a community yard sale a month of so ago.
She made like $60.00 profit.
Everybody else had it for a $1.00 a bottle.
The water cost like .10 cents a bottle at SAMS club, the wife picked it up on sale.
Little girl sat out there most of the day, until the water was gone.
