Someone in the comments of this mentioned 10% off xbox gift-cards which could be used as well.
Blade 17(17.3" FHD 360Hz Laptop, i7-11800H, 16GB RAM, 1TB SSD, RTX3070) may also be an option if you want the larger laptop with a higher refresh rate, but note it's only a 1080p screen. (https://www.jw.com.au/razer-bladepro17-fhd-i7-11800h-16g-1t-...)
Unfortunately no variants available with the RTX 3080 on the Microsoft store, there are older models available with 10th gen cpu's but are about 10-15% slower depending on your usage which may also be an option. (https://www.scorptec.com.au/product/laptops-&-notebooks/gami...)
