Just a note - the signature at the end of installation is the legally binding moment of contract formation.
This is important. If it were otherwise, Dish could get away with making you pay for service from the moment you clicked "order" on the website even before your install date - and could make you pay a cancellation fee if you rejected installation for any reason, even something like NLOS that is arguably "nobody's fault."
