Thanks for the replies. I just signed up online, on the refer a friend site, and opened up another browser, and did an order without it. I got all of the discounts on the refer a friend site that were on the regular site, plus the extra $10 off, so all worked out well.
I don't really understand why the chat guy on the site said that I wouldn't get all of the discounts. It scares me a little bit about D* practices, but they are pretty much my only choice now that Dish has dropped AMC, and all of my RSN's. We have Cablevision here, and they still don't carry the NFL network, so they are out for me.
Anyway, my install is in 2 weeks, and I am pretty excited about getting the HR34. I can't wait to check it out.
