Can you tell me what you did/who you gave a crafty handy to, to get that deal? I'm up for renewal in a couple of months and wasn't going to bother with the 5s given the price they are generally asking for, but if I can get it for that then it's definitely worth it for me.
You'll be lucky

I know a person that works in P4U - he got me a ~£55 contract for £37. I have Friends & Family discount from T-Mob so 40% off £37 = £22.20/m
