This proved to be a nightmare for me because I booked airline tickets at what I thought was a good price on Expedia website and had to go back on the site some days later only to find something called "my scratchpad" offering best guaranteed prices. It was misleading because it only applied if you saw it within 24 hours after you booked. Who knew. So i feel shafted at seeing it in my account and not being able to take advantage of the lower price. Lesson learned. It left a bitter taste in my mouth for the Expedia.com website.
