On Sky World with broadband Unlimited. Called up Sky to unsubscribe from Sky Movies (don't really use it) and Sky Sports (End of football season) and was offered two deals if I kept my package the same, this may be because "I have never taken any deals from sky before and I have been with them a long time"
1. £15 off for 4 months
2. 15% off for 6 months
I took option 1. Can't remember the exact amounts this now will make my bill, but decent saving especially as it is 31 days to cancel channels now anyway. I have to keep package same for that time to get the discount. She even helpfully told me when I would need to call to give 31 days notice of when to end those channels (basically 3 months time)
