Coupons and discounts?

I’ve been trying to buy 26 ultra since the past week. After almost buying it tons of time, I’ve stopped. I’m a student, so I’m eligible for student discounts, and on top of it are there any promo codes for discount ? If none are available right now then when and where can I possibly find codes ?

Any tips will be highly appreciated. Can’t wait to say goodbye to my iPhone and get my hands on it * and runnnn to post it here😂 *
