Back to school offers last date?

Bro till which date this back to school offer will be available.

Do apple deliver the same date promised by Apple in the cart after ordering the device

So far no specific date given bro. it could be by mid or end of october mostly. in USA they set it to first week of october.

And yes, they so far delivered 1 or 2 days earlier from what date they have provided to me. but it may change depending on the location and city service options.

Is it trustable to order devices on Apple.com on the back to school offer

Yes bro. Apple (India) is the Apple India website. I have ordered Mac Studio and recently Macbook Air 15" model. Do record video while unboxing for safety reasons always.
