I just got off the phone with Directv. I am moving and upgraded from the oval 3-LNB dish to the Slimline. I also inquired about the price on the HD-DVRs...when I signed up 1 year ago, they said $399 and they'd give me a $100 credit, so $299. After reading through here today before calling, I though the best offer I'd get would be $199. The guy came back and said $19.99 plus tax for shipping and the HD-DVR is free. I've read about that before, so I jumped on it. Didn't think it would be that easy...
I am a Sunday Ticket subscriber though, with Superfan...and I get all the UFCs in HD...so my bills are rather large...guessing that helps.
It can happen to you!
Keep trying.
