What promotion are you talking about? I'm quite confused about what you're saying. Did ledger promote having two wallets?
When they introduced the nano x, there was an offer to buy 2 wallets at a discount (nano x + nano s).
They promoted is as the 'backup pack', to always have a backup in case your first device gets lost or breaks.
That's quite handy, but not necessary IMO.
I haven't tried recovering my seed in Ledger, and I'm just curious with how you are going to input the seed. Too lazy to search unless I need to.
It is horrible.
You have to go through each word and select each letter using the 'left' and 'right' button, then choosing it by clicking with both buttons.
This can take quite some time until you have entered your 24 words.
You don't need to enter the complete word, it will suggest you words which are in the wordlist and match with what you have entered, but it still an annoying process.
