SPAM £45 off '3' mobile deal, til end December
 

Free vouchers (by email or post) to anyone that wants them, introduce a friend type thing, valid only til end of December.
Worth £30 on a new mobile phone deal and £15 on mobile broadband deal (and I get the same, if a voucher is used).
Redeemable at '3' store, online or by phone.

Helluva deal at moment - only £7 a month for 5G (on top of a £15 mobile deal, 500 mins) I thought it was worth a punt. Has worked fine for for me so far.
