The message 'info - This promotion is not available for your region or your ISP. It has been removed from your cart' will be displayed. The problem is because the giveaway is blocked to certain countries and Internet providers.
It will occur if your country is excluded from the giveaway, these are detailed in https://support.fanatical.com/hc/en-us/articles/360018002197-Promotions-Summary-Terms-and-Conditions
Additionally, we have blocks on certain Internet provider IP ranges. If an IP range has historically been associated with giveaway abuse then this will be blocked. This could also happen if you're using a VPN.
If you get this problem then it might be worth using a smartphone and attempting to collect the giveaway using your mobile 4G/5G data.
If this still doesn't work then I'm sorry, but we won't be able to provide this giveaway to you.
