Is £17 good for sky renewal?

Hi
I just wondered if anyone could advise whether £17 is a good deal for renewing sky basic bundle?

I have been lucky enough to be getting free sky for the last 6 months (no idea how that happened, when I cancelled my sports bundle it took it down to £0!).

They (retention’s team) have said now the lowest they can do is £17, which I think is probably a good deal... but be interested to see if anyone thinks they may drop any lower. Reluctant to cancel completely as my mobile is through them at £6 a month for 2gb data which I know is quite a good deal!

Many thanks in advance.
