Retentions callback

I phoned to cancel on Saturday because the renewal offers weren't great. I had my retentions call back this morning and they offered 1gb BB only for £37 or the package I have now -mega TV, weekend calls (which I don't use anyway) and the 1gb BB for £48 (currently paying 68).

I said I needed a couple of days to think about it - when they phone back will I have more wiggle room, or is likely to be as good as they'll go?
