By no means am I a scalper, but I DO buy multiple copies/qty of "hot shit" when it comes out. I mostly do this so folks around me can enjoy the stuff as well (most of them have kids or an actual life and have ZERO time to fuck around with a PS5 queue).
If I do sell the stuff I buy (a lot of it is given as gifts), it is at retail plus tax. I am more of a "friend reseller" and don't consider it scalping at all.
For example....those DAMN Xenoblade amiibo sold out faster than the zelda totk collectors edition when they dropped at gamestop yesterday.
Also all the folks complaining about "army of bots" (I can only speak for the US here) that was never an issue for me. I have the gamestop, bestbuy, walmart, costco, and target apps on my phone. I was able to secure 5 PS5's at launch for folks at our company with some effort. YES, I had to sign up for notifications from those apps for when items were going to be available, but actually getting them wasn't this dystopian nightmare people like to act like it was (basing this off of my experience of course).
