FWIW I did the same thing and then found out that Dixons had reduced it to £729.99 before I even received it. Emailed them about it and they refunded the difference to my card. I also used the DCBYAW code and got the initial 5% off too. Might be worth sending them an email as you get 14 days to send it back anyway so in theory you could send it back and reorder if they want to be awkward..
Excellent camera too !!!
