I signed up for DirecTV last week using the Costco web site in order to get the $180 rebate. So has anybody actually received the rebate? How long did it take and was there a way to check on it? I am a little concerned because I have received nothing from Costco on this - is that typical? The Costco banner appeared at the top of the DirecTV order pages so I am pretty sure I did everything correctly. Thanks!
