TalkTalk Broadband - where's the catch?

[DonKiddick]

I have seen that TalkTalk are offering a superb deal on their Broadband �3-25 a month, I believe. This is only available if you take their line rental package, which costs about the same as BT''s and also includes free Evening and Weekend landline calls. If I change to TalkTalk line rental will I also be able to sign up to one of those Zero p Per Minute deals where you have to dial a special number like 18666 as a prefix to the UK area code and only pay a 5p connection charge?
Or is there a catch?

My daughter has been with talk talk for quite a while and has had no problems. She pays �20. 99 for phone line, up to 8 meg broadband, 24/7 national calls and some international calls. There is an offer on this package at the moment for new customers �15. 75 for the first 3 months.
