This phone has been posted before but with e2save.
I think this works out a little better (first post for a deal, be kind)!!!
Carphone warehouse are selling this for £19.95 (with £10 airtime).
HOWEVER, if you register the Virgin sim card online (thanks to mouseclick for this), you get £5 + £2 bonus......this makes the phone £2.95!!!!
If you choose to go through quidco, you get £5 cashback.....giving you £2.05 PROFIT!!!!!!
