Given the short supply you won't receive any discount -- they know that if you cancel the order, the next customer waiting will pay full price. If you're looking for the version with the 3060 GPU, they are available at some retailers, in stock and immediately.  If you've a system on order with a higher-line GPU, they're not -- you will need to wait (or buy a different system from someone else). They cannot ship what they can't build, simple as that.  
I ordered an Alienware X17 one months ago. According to the original estimated delivery date, I should already received it. But the fact is that the order status is still "Confirmed", not even entering "Production". And when the so called "estimated date" arrived, I got nothing but just found the delivery date is rudely modified to one month later even without any notification. It is utterly unreasonable at all. Before posting this, I pushed the support for several times, but they keep replying to me like "Your order is expected to leave the factory by this Saturday" and of course they are all not true. And when I ask them is there any delay compensation, they avoid answering but repeating the same words "Your order is expected to leave the factory by this Saturday" again. So I am just helpless and try to find ways to protect my own rights. Actually, I just think it is sort of deceptive throughout the whole process. Anyway, please keep in mind that you are the one who late; please take it seriously, and no more such perfunctory attitudes.
