Are there any deals if you have two devices on Pay Monthly?

[JPWPhoenix]

I currently own an iPhone on Pay Monthly, which is nearly at the end of the contract and will be getting upgraded in a few months. However, I've been considering getting an iPad of some sort too and see that O2 do them on Pay Monthly. I was just wondering if there are any deals for having two devices on the same account? I know both have separate Device & Airtime plans. I'm currently getting Unlimited Data on my iPhone but would probably not use my iPad outside of the home (or would at least only use it in places with WiFi). So, I don't really need to be paying out lots for Airtime/Data for it.

I'm also on Virgin Media for my home broadband, so am getting Volt benefits too (if that makes any difference!).

Yes you can get multisave discount and Volt benefits.

Thanks for all that! It definitely answers my questions and is reassuring to know.
