I'm not sure what you can/will get or not and I will defer to someone who has had experience with this, but whatever offer or details they give you (such as being able to get two SD DVR boxes installed for free 30 days later), get it in writing via e-mail and have them put it in the notes in your account AND read it back to you.
Again, I haven't had the experience of future promises with regard to equipment/new accounts, so hopefully someone who has can give detail on what you should do to assure you get what they're telling you you can get.
I agree with you jluc , however,. the part about noting the account, does not apply wtih direct tv sales, since they use a completely different system than the csr's do, I know this makes no sense, but it is dtv. Direct sales agents have absolutely no way of noting the account. Because they never see the "account" they only see the sales order applilcation, and vice versa. the part of the sales application that sales agents see is very different than the sales;/orders that a csr sees. again this makes no sense, but it is dtv.
