Hello, i want to buy some games before the sale ends, however the ideal payment is not showing up, I mean, it is showing up but clicking on it should allow me to choose the bank I want to pay with, however nothing shows up! What could be the issue? I've tried different browsers, it happens on all of them

As for what's wrong, maybe your bank doesn't recognize GOG as a legitimate business? We're neither your bank nor Ideal's support team, nor will you have any luck getting any timely support from the actual staff because they made the grave error of using Zendesk.

Addendum: If you want something done about this, you may want to mailbag GOG/CDPR via more direct methods of contact.

Probably going to be best if a fellow user from the Netherlands would intervene and inform us what the typical behaviour is and the best course of action, be it a simple "try again later" or "do this instead".

I'm making drm free pizza. Would you like a slice of broccoli and gorgonzola with red onion or pepperoni and sausage with spring onion?
Not staff, can't directly help.
PIZZA GOOD THOUGH!

Its the name of the payment processor yeah! I bought games on the site before, its not the bank because I don't even get to see the list of Banks. Just the ideal option but it opens nothing

Probably they broke it. There was an announcement a while ago that they were "testing undisclosed things on the checkout page". Maybe it got broken or this is the test?
While it doesn't help you short-term and I start feeling like an ad-bot: I think that SEPA would be the ideal (pun intended) payment system, by removing any middleman providers like credit card companies, if only it were accepted by GOG. The WL entry is there:

https://www.gog.com/wishlist/site/sepa_credit_transfer_payment_method_as_an_alternative_payment_method_for_eu_citizen_and_citizens_whose_countries_take_part_at_sepa

I just tested this and can't pay with iDEAL either.
The payment page offers me the option to check it, but the 'Pay for your order now' button at the bottom of the page isn't clickable. Other payment methods work fine. See the attached image.
Contact the staff.

Reading up on IDEAL, it may be part of the transition to WERO:
"European Payments Initiative (EPI) has announced that iDEAL will be replaced by its Wero payment service.[7] Wero is launched in Germany, France and Belgium in mid-2024 as a P2P payment solution, but the service will offer e-commerce/m-commerce payments from mid-2025. The launch of Wero in the Netherlands is currently prepared and foreseen for end 2025/begin 2026, although not much is currently disclosed about how a transition from iDEAL to Wero will take place."
The WERO site doesn't leave a good impression with me but I'm oldscool so don't take well to endless scrolling, large images with only snippet info, and generally being spoken to like Homer Simpsons retarded twin.

While WERO in itself might be a good idea for replacing PayPal, I'd still much prefer SEPA direct payment.

Man i still hope it gets fixed before sale ends ):

I got a response from staff, there are technical difficulties with Ideal, so they disabled it. They don't know when it's gonna work again.

Thanks for the fellow dutchies for checking it out, I hope it gets fixed soon :(

I've got ideal payment porblems as well. Hope tehy fix it real soon before the sale ends!

Do you Dutch chaps have no other means of payment (that you are willing to use)?

We top our pizza with our special "white sauce." Sid Vicious would approve.
You mean apart from the guilder?

You're a complete dafty for thinking this alt is pulling the wool over anybodys eyes GR - especially when you got caught and admitted it before. So shut up you fart wiffling shit gibbon!
