Here is how Bait and Switch works in the Subscription TV industry. NOTE this is an ILLEGAL advertising practice that they seem to get away with.
Basic package: Yoru local network stations and a whole bunch of .. well, ****, Every religion in the world, Languages you can't understand and in the case of DISH, one gem.. NASA
Additional channels are solid in "Packs" as well, again mostly **** but one or two per pack you want, that way you buy a lot of packs adding to the monthly cost.
That said.. I followed the dish Flex Pack link someone provided
The basic package looks rather good to me.. So perhaps they are not using Bait and Switch as much as has been done in days of old.
