Click here for an archive of Cramer's "Mad Money" recaps. "Everything we thought would happen in the '90s when we fell in love with the Web is finally starting to happen," Jim Cramer told the audience of his "Mad Money Main Event II," a special version of the TV show filmed before a live audience Wednesday. Recent strong earnings reports from Google ( GOOG) and Yahoo! ( YHOO) demonstrate there is "still a lot of money to be made online." Google eclipsed Cramer's $350-a-share price target Wednesday, and he unveiled his new price target of $450. That target is based on $9 per share in earnings power and an earnings multiple of 50, he said. "If you're not in it, I still think you can be in it," he said. If you have owned Google from much lower prices, Cramer said not to be a hog. Take a little off the table and let the rest run, he said. Google and Yahoo! notwithstanding, Cramer said the hottest part of the Internet is "the Internet behind the Internet," which is e-commerce. The best way to play e-commerce is through the online bill-payment companies, he said. Their business is "white hot." The two companies that dominate online bill payments are Online Resources ( ORCC) and CheckFree ( CKFR). However, Online Resources is "too speculative for me," said Cramer. He would buy CheckFree, he said, which just reported a great quarter. Cramer also mentioned Digital Insight ( DGIN) as another play on online bill payments but said Digital Insight has had "sluggish revenue growth" compared with CheckFree and Online Resources. Only 20% of people are currently using online banking, said Cramer. There's a lot of growth left. It's "time for you to go check-free and to own the stock," he said. Commenting on Amazon.com ( AMZN), Cramer said the company reported an unimpressive quarter Tuesday. In response to questions about Overstock.com ( OSTK) and IACI/Interactive Corp ( IACI), Cramer said both were sales.
