Hello! I'm about to order the Flex Pack for 37.99/mo plus a Hopper Duo for 10.00/mo. That should be 47.99 plus tax. Should I expect any kind of installation fees or anything? Do the prices of those check out to you? I'm assuming I may get an autopay discount of 5.00 (temporarily). Should I expect my Hopper Duo to go up to 15.00 later? Should I expect this to be month to month or will I need a contract? Will they sell me an OTA adapter so I can record my rabbit ear locals on the Hopper? Thank you!
