The i7 is actually cheaper on amazon right now.

as examples, both of these are 'sold ship by' other places/sources
8g version https://www.amazon.com/Huawei-MateBook-Signature-Laptop-i5-8250U/dp/B07CTKCFFH
16g version https://www.amazon.com/Huawei-MateBook-Signature-Laptop-i5-8250U/dp/B07CTHN94Z
and the amount is not diff, so dunno where profits could be coming from, so i dunno maybe they're getting it direct from the company but that doesnt sound right
I noticed it's now listed on Amazon.com - HERE
UK guy here .. For the original Matebook X Amazon.com was allowing shipping to me with most of the customs charges etc sorted. I thought this might be an option for the X Pro, but now that it's appeared, it's both 'out of stock' and 'not allowing to be shipped to the UK'.
With other brands and devices I've been fond of, they normally have them on the intended UK / Europe sellers sites as pre-orders with an expected arrival date, but nothing like this with Huawei. I'm tired of Googling it lol
Edit. a word
Huawei MateBook X Pro Signature Edition Thin & Light Laptop, 13.9" 3K Touch, 8th Gen i7-8550U, 16 GB RAM, 512 GB SSD, GeForce MX150, 3:2 Aspect Ratio, Office 365 Personal, Space Gray - Mach-W29C https://www.amazon.com/dp/B07CTHN94Z/ref=cm_sw_r_cp_apa_i_u.5cBbES21K52
This is the link. Right now it doesn't show Amazon as a seller, only third party sellers. That's probably why the gift card offer isn't showing.
