Primus £7.99 line rental verses Plus net £11.49

[#1]

How come  New Call Telecom's (Primus)  can offer £7.99 line rental per Month while Plusnet is Up at £11.49
Primus use Openreach  so what am I missing here ?
Thx f9o

Looking at the website it seems at least a pound more than that at 8.99 http://www.primussaver.co.uk/ ?

Even at £8 or £9 per month its still well under plusnet's ?
I see the £7.99 its a 12 month contract,  just wondering if I'm missing something on why their around 30% cheaper....
Thx f9o

actually cheaper to use the 8.99 as you get two months free

Down side is the 18 month tie in on that  offer.
12 months on the £7.99

Primus are operating 12 or 18 Month ROLLING Contracts.
Also, All of the prices they quote EXCLUDE VAT.
Note also that since the takeover, they have inteoduced a 10p Call Connection Charge and have raised their Call rates.

That £7.99 includes according to the T&C of that offer *
"3.1 Subject to clause 19, the prices for the Service shall be as stated in Primus’ tariff sheets as current from time to time.
All prices are inclusive of VAT."

10.5p Connection Charge   not far off the 10.9p with plusnet ?
Those auto renew rollings contracts are slippery, as I found out with BT.  
Thanks f9o

I was switching to them from BT. but changed my mind after I saw the £2.50 for Caller ID 
At £8 fine but at £10.50  The deal I got from BT when I threatened to switch in April is cheaper than that.
