I got that coupon from "spin the wheel"/ "epic fan event" they conducted last week, in the vouchers section it showed the coupon code (I think it was some 12 letter code), pasted it while checking out on samsung store website and the discount got app...
Idk how one can waste money by getting something for free. Also, I'm actually saving money by using old hardware (instead of upgrading my old car stereo)
Samsung Store (website) mein jo bhi in stock hai khareed sakte ho, Yeh type c to 3.5mm wala 699 ka tha, and coupon 1000rs ka tha, toh fukat mein yeh mila mujhe. Powerbank lena tha but stock mein nahi tha ;_;
