Usually the only time I do an alignment is when I replace front end components (tie rod ends, ball joints, etc) or if I notice unusual wear on the tires.
Wheel balancing is usually performed when the tires are put on new and unless the tire has an unusual wear pattern I don’t have it done again unless the tires are sold with FREE lifetime balancing and rotation, then I have it done about every 5-8K miles.
Most cars don’t often need a throttle body cleaning, when I do clean mine I buy aerosol cans of carburetor cleaner and clean it myself for about $3.
For fuel injectors I might add a bottle of injector cleaner available at any auto parts or even Walmart once every 1-2 years, even then it’s probably overkill.
The engine oil may or may not need changing at this point. If most of your driving is short trips where the engine never reaches temperatures to burn off moisture it probably needs changing, but if most trips allow the engine to maintain full operating temperature for 10-15 minutes it’s probably burning off the moisture and I wouldn’t change the oil more than ever 3K miles unless the car is still under warranty and it’s required to have an oil change every 6 months to keep the warranty intact.
Battery water should be free if it’s even applicable. Many car batteries made today are sealed type that can’t have water added to them. Even if they are adding water it’s likely less than 2 oz. to bring it back to the fill lines.
Wheel weights doesn’t make since either. This sounds like you’re being double charged. You’re already paying for wheel balancing, the cost of weights should be included in this unless you’ve got mag wheels and have to use stick on weights.
Brake shoe cleaning? What is this never even heard of it? If they do anything it’s probably only blowing it out with compressed air and maybe spraying on some brake parts cleaner. This needs only be done when getting a brake job.
Greasing the caliper pins might be a good idea every spring to keep the brakes fully functional IF you drive on roads that have been salted regularly throughout the winter, but if the car isn’t driven on salted roads, only when doing a brake job is probably sufficient to keep the calipers free and operating correctly.
I’ve never performed an engine flush on any of my vehicles and my oldest car is 24 years old with 518,700 miles and has probably averaged an oil change about every 4-5K miles since new. Sounds to me like they are giving your wallet a FLUSH. I’d start taking the car to an independent garage for servicing or do it myself if I were you.
I own a '97 Ford Escort that’s only got 32K miles on it and is mostly driven on longer trips 1-2 times a year. Since new it’s averaged an oil change about every 1.5 years. I change the oil every 3K miles regardless of elapsed time and it’s never had any of the other service you have listed except wheel balancing when I put new tires on it and battery water which I added myself.
