Added Snowbird Games to the list.

I can confirm that the Wadjet Eye offer is still good. Sent in an old GOG receipt and got Steam keys for several games.

Yacht Club Games does not provide Steam keys.

I would like to see GOG provide Steam keys for games where and when possible.

How long did it take?
I've sent them e-mail 20 days ago, but they still haven't responded.

Edit: I just received my key. Power of posting, I guess.

This is correct but it should be noted that if one owns these games on Steam and clicks on one of them in the library, there is a "CDKEY" option on the menu with which one can obtain a CDKEY from their Steam game (which is NOT the Steam key as you say), and that CDKEY can be redeemed on GOG. Allegedly however, not all copies of the game on Steam have this CDKEY however, it may depend on where it was obtained or other factors. I own Clear Sky on Steam which I won in a giveaway somewhere IIRC, and that copy did redeem on GOG no problem when I used the CDKEY as mentioned above.

So oddly enough, CDKEYs may exist for these games even if one does not own them on CD/DVD.
That is up to the developers/publishers of the game, not GOG. You'd have to talk to the publishers directly, and some of them do in fact offer Steam keys for their games upon proof of purchase. They may require a screenshot of a digital receipt, a copy of an email receipt, or photocopy of a paper receipt or similar in order to qualify however, and they may not accept gift-copies where no receipt exists as proof of purchase.

GOG really isn't part of that equation, even if someone would like them to be. I'd like Microsoft to give me free copies of Flight Simulator X Deluxe on Steam, as I own it on DVD here. Not likely going to happen. I'd like Walmart to give me a free copy of the toaster oven I bought at Canadian Tire that's wearing out. I'm doubtful but hopeful.

i was shocked today. bought Witcher 3(GOTY edition) from humble bundle. thereafter, then realised that it's a GOG key, not a steam key.
i was taken aback, totally unaware.
Oh well. A $35 price, but got me learning these aspects :
1. check before purchase
2. learnt about the existence of GOG

Welcome to GOG boomzxc!

Thank you!

You have to scroll down past the system requirements to see that it's a GOG key. I agree with you they should have put it a bit more prominently though. I guess for us DRM-free lovers, we're used to searching if it's a Steam key and deciding accordingly (to give it a pass... unless the price is really, really good like that XCOM 2 offer a few months back)

Running With Scissors seems open to giving out Steam keys for GOG owners of Postal games

"We've been having a lot of hiccups with our stuff on GOG, so we're not sure how things will turn out there. If you own our games on GOG, then I can give you a Steam key for them."

EDIT: Confirmation here: https://twitter.com/RWSbleeter/status/955356098621472768

"If you send me a screenshot of your gog library with Postal in it, I'll give you a key."

Better than nothing I guess, but the next question would be, why are they still selling their games on GOG if they feel they have problems supporting their games here?

Most probably the same GOG is still selling a lot of outdated and abandoned games.
