CNET: PS3 for $99.99 (after some work)

[Gannet]

Sorry, buddy, I have received literally thousands of dollars in credit card rewards from credit card companies and you know how much interest I have ever paid -- $0. If you have to avoid credit cards in case it sets off some kind of buying addiction, then the problem isn't really with credit cards, it's that you have an addictive personality. And your book is obviously wrong -- the truly wealthy have tons of personal credit lines. They got to where they were because they built up businesses using credit and they know how to manage them. Most people's net worths are in their homes and investment accounts. This is why this country is often portrayed as having a negative savings rate, because mutual funds and stocks aren't considered savings. But that doesn't necessarily mean every single person splurges all their income on rapidly depreciating assets like blu-ray discs as soon as they receive their paychecks. If you have to read books to understand basic sense personal finance, then you're probably hopeless to begin with.

Here's some expenses I have to pay for in the next month that I'll have to spend no matter what:

Business-related trip to Singapore and Shanghai, China (probably $2,000) -- I can use my personal card and reimbursed from my company
Professional exam fees -- $600-700

That pretty much is the source of free $300 right there.
