If you go directly to the game, you can see Arceus is included:

But you have to have them ships and sold by Amazon for this to work. Kinda sadly Arceus is $54.99. Normally it's nice to save a few bucks, but here it means you only get $54.99 off when trying to do three $60 games if you pick Arceus. edit: you're right that's silly.
There is a search box on the b2g1 page that you can search for games. Mariogolf, skyward, link's awakening, etc are part of it like the target sale. No breath of the wild because it's out of stock ships and sold by amazon. But if you know what games are on sale at target, you can search for them at the Amazon sale page and find most of them. It's not as good as target, but if you have Amazon gift cards to burn or something....
Spent two weeks speaking with a dozen Amazon associates via live chat to obtain my Garchomp Kimono Set. They were clueless about the promotion, and with me having to explain what it’s about, most of the associates confused the bonus code (Mystery Gift) as a game code (redeeming on Nintendo’s website). With that, I went through multiple redirects, and the scripted “24-48 hours” response given to me by the associates, stating that the issue will be resolved within that time span. Two days ago, I finally connected with an associate who understands the issue, and they forwarded my ticket to the promotions and marketing department of Amazon. A little under 24 hours passed by, and I received the code in my inbox. However, I was missing one.. and this was Amazon’s response.
Here’s a screenshot of the pre-order page: https://web.archive.org/web/20220127004408/https://www.amazon.com/Pokemon-Legends-Arceus-Nintendo-Switch/dp/B0914YGQSH
Either I’m blind, or the page doesn’t specifically state that the promotion was limited to one per customer.
Having the same issue. Customer service is giving me the run around and said that I pre ordered the game too early… but I have a screenshot from the day I ordered that said the promotion expired after the 27th. Here is a link to wayback machine as well: https://web.archive.org/web/20220111013729/https://www.amazon.com/Pokemon-Legends-Arceus-Nintendo-Switch/dp/B0914YGQSH
