If you log into your mydish account online, you may see an option for the Preferred Customer Offer (or whatever they are calling it now). If you select that option and agree to a new two-year contract, that will give you whatever the current discount on Top 200 is, with a two-year price lock.
Otherwise, without dropping Top 200, the only other things you could cut would be dropping local channels and/or downgrading your Hopper to a Hopper Duo. Dropping locals would save you $12 per month. If you can get OTA reception, you could still add a dual-tuner OTA adapter to get the locals integrated into your guide that way. It is also possible to add and remove the satellite-delivered locals at will without any penalty. However, that may be too much of a hassle micro-managing your account online to add the locals every day you want to watch them, and then drop them again to save money. Downgrading to a Hopper Duo would save you $5 per month off the DVR fee. You could drop the Joey to save $7 per month, but then you would obviously lose service on your second TV. For a rarely-used TV, it may be a good idea to use a purchased Joey, so it could be added and removed at will, the same way that I mentioned about the satellite-delivered locals.
If you do not have any existing recordings from your Hopper that you absolutely need to save, the cheapest option would be to simply start over with a Wally. Adding an external hard drive and paying a one-time $40 fee would convert the Wally into a DVR with no monthly fee. Make it clear to Dish that you are making this change to try to save money, and you may be able to talk them into waiving that $40 fee. Add a purchased Wally for the second TV, and it can be deactivated and activated when needed, just like I mentioned about the Joey earlier. Keeping the second Wally activated full-time would cost the same $7 per month fee that the Joey currently costs. One drawback of the Wally system is that the Wally receivers do not integrate with each other, though. That means no watching recordings from one room in another room, unless you manually swap the external hard drive from one Wally to the other one.
