If you don't have a need for bottled urine, perhaps you'd like to purchase some worm poop? According to TerraCycle Inc. <http://www.terracycle.net/products/43-Lawn-Fertilizer> , worm poop is an ideal, natural fertilizer. That is why they package the naturally occurring waste in used 20-ounce soda bottles and sell it for $7.99 (prices may vary). Proving where there's worm waste and soda drinkers, there's money to be made.
