I think I got ripped off, some comments please?

****, that water pump was expensive. but you didn't get ripped off. however, anytime you do a timing belt job, you MUST do all the seals as well, which you did not. If the cam shaft seal or crank shaft seal starts leaking oil, your gonna have to pay a mechanic to go back in there for another $300 because of the labor, rather than if you just did the seals while doing the timing belt it would have cost $40 cause its down there next to the timing belt.
