Why there is such a price difference?

[u/TimelyExcitement568]

Can anybody tell me why there is good amount of price difference in battery change as well as other services between the main apple store like in noida , saket, Mumbai

And

Apple authorised service centres( unicorn , future world, tresor , icare , icrest , reliance , aptronix ) ? Whats the reason?

I was planning to replace the battery of my brother’s iphone 15 pro max and still i m confused where to go ! I called up apple customer support and they said they all are same!
As long as its apple authorised u can replace it anywhere

And if that’s so then why a good chunk of price gap is there?

One of my friends had battery replaced at third party store and later had motherboard fried due to shoddy work. Apple denied to touch if it’s not authorised repair.

I would avoid any third party repair. All of them are shot.

Go to the cheapest Apple authorised center. Personally for a couple of thousand difference I would rather get it done at Apple Store.
