I already have a 600D from last year, but this looks a good deal from Askdirect (not updated on Camerapricebuster yet).
£529 less £50 from ASK, less £50 cashback from Canon (which I claimed last year without any problem), plus Wifi card from Canon and case and 32GB memory card from ASK.
Free delivery or collect from their store.
I have only used ASK once for a PC battery, but that was delivered without any problem.
