I think this is the cheapest going rate for an oil change because it's $5 to dispose of your oil. I get a special drop-off-your-oil-at-night-when-shop-is-closed discount though.

Just make sure you got a new oil filter and your oil looks clear. Or watch them drain your oil. At the very least, you have to check your dipstick right?! You can see the new oil is much clearer.
Midas did rip me off. They charged me $750 for a radiator change (cost of my car practically). $350 for a radiator part. I looked it up and it was $250 retail for the top of the line radiator for my car @ Autozone nextdoor. Like seriously, a mark up over retail isn't smart when they could have easily marked up their labor hours. I could have went nextdoor bought the radiator and walked over and say, install this...save $100. No, they don't have to buy the part for you on this location. Oh and they went $20 over their estimate and didn't tell me. I disputed that and got the quoted price.
Do your homework people! Trust no mechanic, doctor, dentist, or anyone that charges a fee for services rendered. Not even if you've been going to them for years.
