digital outlets Advertising products not in stock Internet

I called to verify that they had and could ship a lens before ordering.  Even paid for 2 day shipping to guarantee I would have it for an upcomming trip.  They confirmed that it was in stock and the unusually low price was correct.  It was low even for an import model, so I was suspicious from the start.  They charged my credit card when the order was placed.  Next day, I reveived an email to call and confirm the order (for security purposes).  When I did, I was told they the lens was not in stock and they did not know when it would arrive.  Seems like a deliberate effort to advertise a product below cost that they have no intention of selling.  They did however refund the purchase price back to my credit card.
