Gone way down hill

I used to trust this app for all my flight bookings. Now you cant trust it. Be very careful as the price quoted will change when you go to book it. If you dont notice the change you will pay substantially higher price and the fare is non-refundable. Example. I have been trying to book Calgary to Vegas for several days. It quotes me $375 return. When I try to purchase the price changes to $534. Not a small change
