Please help out a student

So im a student 18M studying at a nit. So, for the past 2 years ive done odd jobs and stuff like just helping people around or just some sort of work to earn some money and i have collected around 10k~ within the past 2 years. Now i want to buy sony ult wear before april or so, but its at like 14.5k, and i cannot get the extra 4.5 cus i need to focus on CG and college works, so any tips/coupons anyone can provide so i can get the headphones for around 10k ish~

Thank you!!
