Line rental saver - Should I renew?

[#1]

I'm on an 18-month contract and my line rental saver is up for renewal. If I renew it will take me 6 months past my current contract. I don't know how much I would be paying then and signing up for another 12 or 18 months would take me past the line rental saver period. It would be much easier if I could renew my line rental and broadband at the same time. As it stands I might just pay more for my line rental for 6 months then see what's available.

I imagine it depends how likely you’ll renew your contract when it’s up for renewal. I believe line rental saver is due to be withdrawn from sale later this month so you’ll need to buy it quick one last time if you do want it
