Ledger Wallet NFT "Code Invalid"

Is anyone else experiencing this?
When I claim my Ledger Stax NFT at shop.ledger.com/products/ledger-stax-redeem, it says my NFT is valid and available to claim. Yet when I select "Checkout now" I still need to pay over $300? What's the utility of the NFT then? Wasn't it a premint for the Stax, and why am I paying again?
