No it is not a bug, its a feature. Dependable on country... and yes this is a DRM... the prices can be up to 50% or even more increased compared to the cheapest offers. In extreme cases "the discounted prices is same for us comparable to the normal prices elsewhere". Still, in average the price increase is around 20% vs. US customers and even some other stuff is affected; for example the PS5 Pro was way pricier there as well. Taking the way lower MWST/VAT into account... even Sweden is cheaper because they got over 20% MWST/VAT, not 8.1% only. Same for the EU...
However: Steam or almost any other place is not different. GOG is simply "adapting" to the robbery-standards which is considered legitime.
Long time ago, when GOG was not using regional pricing: I was buying several times more games at the full price in order to support DRM free. Nowadays, i (almost) completely stopped doing it and i try to get the cheapest deals possible everywhere... because my "good mood" has stopped in most cases (some exceptions are possible dependable on dev/publisher). Even if i use sales... i still pay way more than others. The most fair prices i do get by using keys... but my policy is to use them on Steam and EGS only and yes... i can save up like crazy by using them all the time.
My recommendations are simply: Always look out for sales, there are a lot of them and even keys could be a solution (more likely on Steam... i use them on Steam/EGS only, with the exception of presents).
Sure, if the robbery is going even more crazy... there is even the option to use a second account and then "handing over keys" to the main account or even simply ask a friend from another country to "buy stuff for you". Surely, the "red line" is very close... and some people with way better regional pricing are still moaning about their prices, including related to Stalker 2.
I just can say... sometimes it is just ugly "how much coins can be saved up by using a key". Sometimes the regular price for my country is like 90 CHF on Steam but by using a key i can get the same game at perhaps 30 CHF. I mean... it is A LOT of bread and milk for me... doing it and i got other costs in my life as well. Those who CAN... they should simply pay this price asked but this is not always a requirement.
A game i am interested in, but it is just a rip off... to be very blunt, so i am resisting getting it. Of course "worst case" but there are many comparable examples, including GOG:

Yes, up to 80% increased prices... and another problem: It is very hard getting a good key for it.
I feel like... in many cases the publishers are just playing a marketing game... and are guessing how much cash they can "rip off" of someone. The Mexico price is crazy as well, for this game... and yes, i feel it is "discrimination".
Anyway, if the difference is lower than 20% vs. US i am already happy...
Cavalary: Welcome to the wonders of regional pricing... Yeah, Swiss customers generally get the very worst of it.
And do better to compare to the US (base) price too, USD comparison since it's available everywhere:
DK: $107.27
US (base): $109.99
NO: $110.84
UK: $113.85
EU except SE&DK: $120.59
SE: $122.19
CH: $141.09
Tends to be more or less the going rate...
The true issue is: The "other" countries with way bigger inflation in average got a higher increase in salary than what we get in our country. Because they say "we had a very low inflation, so the increase in salary is very low as well"... and i dunno how they even calculated it because when i look at certain insurances (the car insurance has increased by 20% in just a single year), health costs, ONLINE game costs, costs for renting a home... or what else... i see like 50% inflation in just a couple of years... but almost no one got a 50% increased salary.
Sure, not even in the other countries... but... at least those countries are not telling them "we had a very low inflation"...
Anyway, nope... no one was taking "real economics" into account... the publishers in many cases simply want to get out the maximum possible... and are trying to always scratch "the red lines", sometimes even mixed with discrimination... just very few of them are trying "to be fair".
