Don't worry about it, it will come up again eventually.

Tried it multiple times here on GOG. It doesn't work as described: recipients redeem the codes and proceed to not play the games, or sell them to potential fans who could've otherwise bought a copy (effectively, sponsoring someone's CS:GO habit).

Well, I meant more like giving the spares to actual friends, people that one knows will try the game at some point, not Internet randos. I've never been into "random acts of kindness" gifting exactly because of the high likelihood of the things you described occurring.
By the same token, I rarely accept (paid) gifts, enter giveaways, etc., because I'd rather not feel pressured to play a game I'm only kinda interested in just because someone gave it to me (or, for that matter, take a copy away from someone else who might really love it).

Having worked in this exact industry:

Sales are when the developers (and the store) REALLY make the bank. The volume more than makes up for any discount offered. And when I say "more than makes up," what I mean is "ZOMG MORE THAN MAKES UP!!!!!!!!111!!!1!!oneone"

Thank you all for your feedback.

I've subbed to the items in my wish list. Let's hope they go on sale again soon!

In addition to the good info others have provided above, I'd like to also suggest checking out http://www.isthereanydeal.com which is a site that tracks the price of video games across all online stores over time. They have a complete history of game prices going back several years on all stores which can be shown as a graph to compare prices and aide in predicting when a game will go on sale on a given site and at what approximate price likely. It's one of the best tools available for bargain shopping for games on any store, and if you create an account there you can also import your wishlists from Steam, GOG and other sites and receive notifications not only when a game goes on sale somewhere, but at the specific maximum price you specify and/or at a specific discount or greater. The site has a tonne of other great features for maximizing bargain shopping for games and is probably the easiest "one stop shop" for this kind of information about games online.

Best luck bargain shopping! :)

Thanks man, that´s exactly what I wanted to hear. My bitter agony is gone!

Somebody always remembers. Thank you for that! +1
