Call Shaw direct and see what they would offer you to switch to them and then call and ask for the loyalty dept at Bell.
Earlier this year, A Shaw TV (Starchoice) came to my door selling when he found out i was with bell he offered me a free hd receiver and some programming. I waited a week and called Bell and spoke with the loyalty dept and right off the top the gentleman on the other end offered me a HD receiver rental free for 2 years or a HD PVR rental free for a year. The install was included. The install included the new dual lnb, dish and switch and 1 run into the receiver in the house.
