Can anyone explain what prompted Six Flags to buy 100 of these, or what has everyone excited?  First-aid vending machines aren&#x27;t new, nor are these products that Six Flags doesn&#x27;t currently sell.  You can already buy some of this stuff at gift shops, and everything else is (and should be) handled by EMT on site.<p>Not saying this isn&#x27;t a novel idea, just haven&#x27;t wrapped my head around the business model that hasn&#x27;t already been done before, so I feel like I&#x27;m missing something.  Is it increased visibility in park leading to more sales?  Ability to eliminate some EMT staff?  Ability to charge people for supplies instead of giving them away?
