The reason why the ad in Newegg doesn't show the promotion of for the RX5700XT is because it ended already and was replaced by a new AMD Promotion but for the RX570 and RX580 GPUs.
This the latest AMD Promotion concerning GPUs: Q2 2020 AMD Radeon™ SI Game Bundle Promotion - But this latest and current AMD Promotion is for the RX 570 and RX580 GPUs only.
The AMD Promotion for the RX5700 Series GPUs was this one: Q1 2020 AMD Radeon™ Raise the Game Bundle Promotion
So you will need to purchase a RX570 or RX580 to get a different game.
