How can I speed up fetching pages with urllib2 in python?

I have a script that fetches several web pages and parses the info.

(An example can be seen at http://bluedevilbooks.com/search/?DEPT=MATH&CLASS=103&SEC=01 )

I ran cProfile on it, and as I assumed, urlopen takes up a lot of time. Is there a way to fetch the pages faster? Or a way to fetch several pages at once? I'll do whatever is simplest, as I'm new to python and web developing.

Thanks in advance! :)

UPDATE: I have a function called fetchURLs(), which I use to make an array of the URLs I need so something like urls = fetchURLS().The URLS are all XML files from Amazon and eBay APIs (which confuses me as to why it takes so long to load, maybe my webhost is slow?)

What I need to do is load each URL, read each page, and send that data to another part of the script which will parse and display the data.

Note that I can't do the latter part until ALL of the pages have been fetched, that's what my issue is.

Also, my host limits me to 25 processes at a time, I believe, so whatever is easiest on the server would be nice :)
