i took out the G600 which cost extra 14.99 but though it was a ace deal been as i had alot of credit on virgin network anywayz.
P&P = 3.99
Total cost (12x18)+(14.99)+(3.99)=£234.98 for 18 months.
so 18 months and no need to claim cash back. Also worth getting ya credit off ebay usually costs £14 for £20 credit. which can be added to a contract on virgin. making the credit cost roughly (£151)
