It was bought at Home Depot.  Basically...the sales associate "sold" our son on buying this model and this is the one the associate handed him to buy.  Was it possibly sold and returned by someone?  As we examine the box...it is glued on one end and taped on the other.  There is also only one piece of styrofoam in the package and it looks that there should be two.

I am expecting a speedy solution to this situation.
