Seems a good price for a larger 46" Plasma TV with Freeview HD - the price when launched this year was over £1000. Also available from Currys for £671 (use discount code SALES6). Quidco 3% for Dixons. Also available from John Lewis for £714 with 5 year guarantee which is actually where I bought it from.
Use code REEVTV40 for £40 discount off listed price of £669.
