It may have been a glitch or we may have problems in the coming months.

Probably just the standard 'it's out of stock, so some random seller will throw it up there for 2-3x the price and hope someone buys it' that just about every product has on Amazon. I see it happen all the time with board games.
Like this card pack for the Arkham Horror Card game, that someone's trying to sell for $40, when it retails for $15: https://www.amazon.com/Arkham-Horror-TCG-Dagon-Mythos/dp/B08...
100% the fault of Amazon or whatever marketplace this is. Right now we should be having a rich taxonomy and unique product database that links all versions of the same product together so that I can click: "Chewy Dog Food 5kg" and get all the sellers offering it. Then proceed to sort by price, filter out the suppliers that look dodgy, add said suppliers to a "fake chinese product spam list" personal black list, and proceed to buy the cheapest original version of the product.
