There is something you need to take note.
Dell has 2 segments
1. For Home
2. For Small and Medium Business
The coupon is segment specific.
For example at first I add the monitor to the cart through Home segment.
Applied the coupon but it's invalid.
So I remove the item from the cart and add again through Business segment.
Voila, the coupon just save me $100.
Just get the code from the website and paste into the coupon box during checkout.

Remember to say thanks if it save you a few hundreds
