Price includes payment fee and using the discount code: HOTUKDEALS
Seems to be a misprice as the standard edition is priced at 149 SAR, whereas the digital deluxe is priced at 45 SAR.
Pretty straight forward, first purchase 50 SAR from eneba via the main link. Then either use a VPN to redeem the code on microsoft.com
or change the console location settings to Saudi Arabia, no VPN needed.
