FYII'm in Bombay and couple of days back, we (our building society) called a TS sales guy to give us a demo of their services at our premises. Presently, TS has an offer of 3 months free viewing. The sales guy offered us 2 more months of free viewing (ie total of 5 months free) if ten members (we have 21 flats in total) in our building agree to sign up for TS.So if you are in a bldg, try to convince your society and get something off either in terms of free viewing or a discount on installation costs.If you ask the helpline, you get mixed response about this. Some say that there is absolutely no room for any haggling while others say that there is some scope for a discount and it's up to the sales guy.
