What would you guys do in this case of a Pricing error(tho i only believe it for one card not all i bought)?

Hello everyone I am asking for advice/your opinions on a weird pricing (error)?

I was browsing Cm yesterday for card because i love cards.

I checked out some Presales and what immediatly caught my attention was that one seller(professional almost 10k sales) had significantly lower prices than others.

There were around 5-6 cards in the set everyone put on presale at 400-500€ and another 4ish to around 250+

And this one guy he put all of it between 20-30€ amd even one at 2€

One for 2€ (i call it Card 1) and one for 28€ (I call it Card 2)

So heres the weird thing

Card 1 the next lowest listing was 399€ vs his 2€

So i assumed he meant to maybe put it as 200€?

But how do you miss 2 zeros. Maybe onput lag or so or he put 200 but accidentally put a . Or , between the first two digits so I assume he will try to cancel as soon as i order.

5 minutes later I checked the card again to see if he relisted and the guy had put up more copies of it at 55€ meaning theres no way he meant to have them at 200€

The rest of the 2€ got bought really quick aswell i only got 1 because i only need 1 and i dont belive ill ever see that card amyways)

So now I am even more confused

The 2€ before were not meant to be 200 but 20? Which goes hand in hand with the other prices he had because most of his card of the chase were priced between 19.95-30.00.

Were as most other sellers had the 19.95 cards at 350 and the 29.95 card between 399-550 even.

Next weird thing, throughout the night i saw that card being bought until the 55€ offer got bought out by 9/10 am because at 8.50ish before work clock in i saw it was still there goong down in quantities. Then he relisted them again at 120€ around lunch time vs everyone elses was between 350-450+

Right now when I checked before posting (6.45pm) he has another copy up at 135 (1 left) and others started listing, one at 150 and next cheapest at 300

At this point I cant imagine it being a huge typo

I think the 2€ was meant to be 20 considering he sold the rest of chase cards at around that price

So I then checked Card 2 which i got for 28€

The lowest listing was 399€

And the card got bought out at 28 and again that seller put up new copies at 100€ vs rest being at 399+ mark which eliminates my theorie that he meant to put 280 because why would he then put 100? Which currently is still there as an offer at 100 while rest being in the 3-400s

I talked to some friends and some of them also bought some card (2-3 in each case). All of us are not expecting it to go through. None have paid yet since we expect cancellation requests

Current State

I bought the cards but have not paid yet. Because i am expecting a cancellation request tbh.

Set releases next thursday and i bought the cards yesterday evening

My current thought is to wait till tuesday/wednesday to see how the price is changing since this is presales. Hoping they get closer to the price i bought them at. I really want those cards because they are perfect for my favourite deck and a new illustration for my favourite card. And i could never afford the outraging prices the others put.

I dont plan to resell those. I just want them tbh ahahah

I also have screenshots of their listings afterwards so I have proof of their price development showing that it was not a typo but he just didnt value the cards the way others did. Is that fair to say?

Id really love to get hold of the 28€ card

I dont expect the 2€ to go through and if somehow the sales end up being 200+€ for each i would feel bad insisting on the sale.

What would you guys do? And how do you think it would resolve.
