It does not appear to be working from YVR any longer, so I think they probably finally pulled it altogether.
The american site made this mistake a while back, and I was able to take a trip to Vegas for $85 all in, car, hotel, air and taxes and resort fee for 5 nights during a busy weekend in Oct.
I have a friend that used to do accounting for a travel agency that Expedia bought out. She finally quit because she could not stand that they had no accountability at all. She said that they had no way of knowing if they had been paid by their corporate clients or not, and really didnt seem to care. Weird way to run a business.
