darren24 Found this over on HDUK but have tried it and seems to work on irish mobiles too.
Details:
Maybe not a deal as such but I just discovered how to use up unwanted PAYG SIM credit to pay for apps on Google Play. I believe the same method will work on IOS devices. This works on EE, O2 and Three. EE (Chitterchatter) often have PAYG SIM cards on eBay with £5 credit for a quid so this is a very cheap way to buy apps, music and movies.
I don’t have an Apple device so I haven’t tested it but O2 has a link to doing this

and I suspect that other providers will do it too.
1. (optional) remove your usual SIM from your phone and insert the SIM with the unwanted credit.
2. Start up your phone and turn on data (even if WiFi is on).
3. Open Google Play, go to My Account, Payment Methods, Add Payment Method, Mobile Billing.
4. Choose whatever paid-for app you want and make sure you select Mobile Billing as the payment method.
5. You can now stick your usual SIM back in your phone but you will still be able to charge apps to your SIM with the unwanted credit. The payment method also shows up in other devices such as tablets.
6. Once your credit has been used up, go to Google Wallet

on your PC and remove the mobile billing facility for that SIM card.
7. Repeat as required!
looks like you can buy movies and music as well…not just apps.
