Remember these?  I used to drink them all the time, and they were THE preferred juice box in grade school.  Someone ended up hanging onto one of them, unopened! 

Here's what the description read on Ebay:

   Hi, you are bidding on an unopened Hi-C Ecto Cooler juice box with straw which is unopened as well. I have never seen one of these before, so I would think that these are very rare. Would be great for any Ghostbusters fan or Coca Cola fan since they manufactured the product. If you have any questions, please feel free to ask.

 

The bid closed out on June 18th, with the winning bid of $515.
