Used Yoee.com to buy two tickets on MU PEK-XIY-PEK, out this Friday AM, back on Saturday PM. Outbound the discount from coach (1050Y) was 45% and 55% on the return (This was substantially better than what CTrip was offering, for the same flights). Still waiting for a confirmation email, but will go to the MU eticket counter on arrival in PEK Wednesday to make sure everything is OK. The website is a little 'funky'.
