When I go to my wishlist, these games are listed as 'FREE' but when I add them to the cart and checkout I get billed anyway.

Does anybody know if they should be free as part of a promotion of the current sale?
Did anybody else have this strange issue?

Yes, it looks like a glitch in the wishlist and I see the game thing (eg, Blade Runner is "Free" in the Wishlist) but clicking on it takes you to the store page where the price is normal with a -20% discount (£8.19 discounted to £6.59 for me). The checkout cart shows the same price.

Edit: I've also seen a couple of "Error 503 Backend fetch failed" page-load messages over the past couple of hours. Probably some server issue.

This happens sometimes when GOG's website is under heavy stress. So not really free.

Best one is seeing Cyberpunk 2077 free. Don't tease me like that GOG, that's just mean! xD

I thought I was hallucinating. For me, the following games are free in the wishlist (I wish though), but in cart it shows original discounted price:
* Crysis
* Dragon Age
* Kenshi
* Kerbal Space Program
* No Man's Sky

Well...it's a free glitch at least. Hooray?

Thanks for all the replied.
Yeah it would be cool to see Cyberpunk 2077 FREE ;)
