Okay, so your base package is around $70 a month. That leaves another $40 you are getting charged for additional features.
You don't mention any Premium Channels, so I'll assume there's no charge for that.
No Whole Home DVR.
2 HD DVR's and 1 SD DVR. So if you have only a total of 3 receivers, there's an additional $12 charge there.
You have HD DVR's, so that would lead me to believe you are getting charged $10 a month for the HD Access Fee.
The DVR fee is $8 a month.
If you have the Protection Plan, that's another $6 a month.
Now we're up to an additional $36 per month.
Do you use AutoPay? You can possibly still get the $10 HD Access Fee credited if you use AutoPay. Doesn't hurt to call and ask.
If you have the Protection Plan, you might consider dropping it. Have you had to use it to get your dish realigned, replace the LNB, multi-switch or anything like that? That is a risk/reward thing that you'll have to decide for yourself, but that would save you $6 a month.
Those 2 items alone would drop your bill by $16. You could also just try calling and see if there are any other credits that you might be eligible for. If you're not under a commitment, they may give you more. It can't hurt to ask.
Right now, I'm getting the following credits: $10 HD Access Fee, $5 a month off my base package for 24 months, 1/2 off Starz for 6 months and $5 off a month on HBO for 6 months.
