I booked the iphone 17 for 78,990, at Imagine. Now i think its expensive. Can anyone tell if its expensive as compared to other stores like reliance digital, croma, or other.

I dont have unicorn store and also green wasnt available on flipkart.
Also if i get to know its expensive, can i cancel the booking as i paid 2k in advance, because they said they have a sale on 19 where they give a speaker and you have to pre book. (imagine people said this).
