Car repair price question: water Pump?

I took my car to a repair shop today, cause it was overheating,
After looking at it for a few minutes the mechanic told me that it was a water pump problem.
They quoted me a price of $276 to totally replace it
I called around to my local auto zone stores and found out that the actuall pump cost for a new pump was $39 dollars, and I can get rebuilt pumps for 19 bucks,
Is it that labor intensive that it would take so long to put in a 39 dollar part for over 200 bucks labor. Is that a fair deal, or am I getting ripped off.

My water pump costed 505 dollars to replace because it ruined other cooling unit components when it went. There is a bit of work to it, but the make and year of the car has a lot to do with it. I had a ’94 Olds that did this and with them, you have to remove several engine parts just to get to simple things, let alone the more complicated stuff. $276 is a reasonable price for this to be done at a garage. The cheaper the water pump, the lesser that quality sometimes, and it may not last as long. Good luck!
