EXPEDIA Expedia book together and save $ Internet

Booked flight & hotel for 2, then kept wondering why they charged me the same cost as if I just book each individually. Tried their site a week later and then got the "you booked together and saved $118" which didn't show up when I booked. Though it was advertised that I would save money. I called customer service who said there was nothing they could do, because I didn't call within 24 hours to "address this." Lousy customer service, bait and switch. Don't ever use EXPEDIA.com
