Game consoles and incidentals.
Others earlier were imagining the game shops would lose out if the bots buy them rather than buying overpriced sweeties, little statues of pop culture figures and whatever other high profit nonsense they do as the scalpers/bots would presumably not be buying that (at least until bot detection algos note it and like spammers doing aoihgdkjghfkjghfkjfh in the middle of their email to weight word filtering, possibly to return later once they evaded and items were delivered).
I imagine however the game shops/whatever selling them have very long lists of people buying game consoles at launch and whatever else it is they sell going back decades now (

Despite me not having access to those lists I have been at several or spoken to those that man the shops over the decades now.
Singles sell out, maybe with a game, maybe with another controller (granted split screen at this point in time is a largely forgotten affair).
Bundles sell out next, unless it is a rare one which tends not to be console launch. Unless it is the UK and in that case Game/EB often shrink wrapped a crap game with it and people tended to resent that, especially when it represented "most" (read all but I can't prove it for every occasion) of the stock.
Nobody however is browsing and buying junk. Straight business those nights/periods.
Anyway beyond that if all these bots and scalpers are rocking up with straight cash then you don't simultaneously end up with a bunch of second hand PS4s and xbones (and phones and bad games and whatever else such shops take) to deal with both on the night and going forward (if you now have 500 of the things you lack the space and have to drop prices, to say nothing of Sony/MS presumably wanting their cut while you sit there with all the money tied up in second hand PS4s nobody wants because it is old news).
Another that some might be concerned with is if all the PS5s in a middle income area get bought out and sent off to the rich area that the middle income shop will not see any game sales. Maybe not at first but in a month or three when stock comes back in and the kids that saved up for a while to get one can get one (or get another if they flipped their preorder for profit) they will be back just the same, which also will be choice timing as you might actually have some games worth playing.
