Is the internet a good tool for finding a good deal?

[Joe L.]

I'm getting mixed messages regarding finding deals on the internet. I'm looking to fix and flip and some people tell me "don't waste your time looking online, if it was a good deal it wouldn't have ended up on Zillow, Trulia, Auction.com etc" and yet, others, say they spend hours online looking for deals.

My question is, what is your experience with finding deals online? and are the websites I mentioned above a good tool for investors in finding a deal? or should I rather spend my energy networking and calling brokers?
