Negotiating as a new customer

goingonholiday_2

I have 2 contracts, one for me, one for daughter and my wife has a contract, all with 3. 2 of the contracts are up and one is about to finish, would continue with 3 as reception issues appear to have been sorted out but not overly impressed with their phone options (and so far their retentions team are persistent but not offering anything worth taking).

So, has anyone had any luck negotiating as a new customer for one contract or multiple contracts (could easily do all 3 in one name if needed)? Will probably just try anyway but would help if I knew if anyone had got any good discounts.

I'm thinking Blackberry, wife not sure, daughter wants an iphone (typical) but it's all up for negotiation! Probably looking at 600 mins and internet (and email if blackberry).

Thanks
