It's not just scalpers but certain retailers you have to be careful of, especially depending on your region.
Just to give an update, the $1320 NZD MSRP model 9070XT is still available to pre-order at that price right now, at least here. The cheapest 5070Ti is still $1900 NZD.
Anyone talking about retailers cancelling pre-orders just to re-list the products with increased prices, I've seen no evidence of that happening here just yet. Time will tell but we still can't say for certain that's a universal issue. More likely it's just retailers in certain parts of the world taking the piss. Seems like Europe (including the UK) are being hit the hardest right now, followed by Canada. Condolences to anyone there.
Microcenter so far are the real MVP. They're making the case for why a human presence is still necessary for these kinds of launches. It's the only surefire control method to bypass scalping. You're still then relying on the goodwill on the retailer's side, which is why you should value the good ones while you have them.
Rewarding bad retailers and scalpers on the other hand only contributes to the problem. If the market in a region still isn't reasonable it's better for people there to just hold out if they can. If they can see enough of these products are being supplied to other parts of the world while their own local dealers are screwing them over, there's no way they should stand for it.
