Question:
While Disney pays less for their water than 7-11, I'm sure you'll find that any business receives discounts in bulk orders of most any product. No conspiracy hereany ideas?

Answer: I'm sure WDW would love to cut the cost of labor moving product around their city-sized property. I'm also sure that waaaaay too many of the "Disney is losing it's magic whiners" would defacate gold bricks over the site of delivery trucks in theme parks.

No one may use the argument of backstage delivery. We all know how closely WDW guards its secrets and it would be way too easy for Universal or Busch Entertainment to pay a delivery guy to take some pictures backstage for them.

Therefore, to use Lowell's idea, you either have Disney employees distributing backstage or you have non-Disney delivery trucks in site of guests.
