We are all users here in the forum. Any discounts should come directly from Dell. Those coupon sites might be spreading malware. 

Ye I am not using any 3rd party site, I just try to get a coupon from Dell official representatives because its unfair to give discounts from phone and not from chat...

I read numerous stories about people getting coupons for their new systems.

As with anything, manufacturers will only discount when they have to -- and since notebooks (more specifically, components needed to build notebooks) are in short supply, there's little or no incentive for manufacturers to provide discounts.  For every buyer waiting for a coupon code, there are multiple buyers lined up paying full price. 

The market for notebooks -- particularly those using higher end gaming GPUs -- is a seller's dream right now, and a buyer's nightmare.  That looks like it won't change until 2022 at the earliest.

agree but this doesnt seem to be the case for everybuyer judging from the comments I have read

Don't trust on these coupon sites
