We sold 4 phones including a Samsung G600 which had a back that wouldnt stay on and they quoted £90 for a cheque or £97 if we wanted payment in Argos vouchers, took the Argos voucher option, they collected by courier from my work the next day foc as we were trading in 4 phones and 2 days later got the Argos vouchers for £97 as quoted.
I would def use them again
