Probably the cheapest 1440p 144hz monitor out there, don't know personally the quality but on paper doesn't look to shabby. At the very least you get $50 steam card for your troubles.
Price breakdown as such: buy 5 giftcards (4x$100 1x$20) @ 15% off is $357, then pay the extra $19. There might be other ways to get it cheaper
(referrals etc.) but Unidays doesn't work as it is a marketplace item
