I noticed this morning that Games Republic was added to the listings for Monster Hunter World: Iceborne. I thought I'd give them a shot
https://gg.deals/dlc/monster-hunter-world-iceborne/
I placed my order at about 10AM BST, didn't receive my code for an hour, so I emailed support@gamesrepublic.com
It's now almost 3PM BST and still no code or reply
So fair warning, I wouldn't recommend anyone else to try ordering with them right now
