good travel deals?

Does anyone know a good travel agent or a good website for travel deals?
We want to goto London and Ireland & I've been looking into different options for a while but everything's so expensive so I thought you girls might have some recommendations on where to look for cheap flights or package deals.

i posted a question a couple weeks ago & the responses were helpful ( i don't want any of you girls to think I'm not taking your advice or i don't appreciate it) I could just use more thanks!

I always check airfare on www.kayak.com. It searches flights from all of the airlines, expedia, hotwire, etc., in one easy search.

For travel to Ireland - I always found the best deals through sceptre tours. I think they're located in Rockville Centre.

Happy Planning!
