Was my go to place, bought on 250 dollar Asus monitor from this place about a month ago. Cashier asked me if I wanted a warranty that covered everything which I said yes. Now I have a scratch on the screen and I come to swap it out and they tell me it's not covered. Are you kidding. Wasted my time and money here. Go to Best buy people.
