Well I did an online chat and Edward did my main account and I asked him point blank in about 3 different ways , is it for the LIFE Of you Account as long as you stay current and with DISH and he said yes. I did my second account for my parents with Rechelle and she wasn't as forth coming, till I put it to her the same way and she said that the promotion ends in December. I asked again so is it for 6 months or is for the LIFE OF THE Account? She said it was for the life of the account and there is NO end date at this time for HBO.
Knowing DISH and the history I've had with them , I doubt very seriously that it will keep going on. Kind of like the 501 dvr and NO dvr FEE for the life of the receiver! They charged a dvr fee eventually. The Second Hopper on your account will not go up and stay only $7.00! I even said at the time , it would be bait and switch if they went up on the price after everyone got a second hopper ,since the price was so low -compared to the $17.00 fee for a second 722k on your account. But that sure didn't pan out, did it? Ended up with $12.00 and DISH had to pay $5.00 credits for like 2 years, to soften the blow.
Either way I have HBO for only $10.00 for now on two of my accounts. Will come back in December and see if it goes up ,and I won't be surprised if it does. After all, it says in their disclosure small print that they can change the price at any time for any reason, along with add or drop channels .
