I made a purchase from the sale a little while ago and I still don't own Rebel Galaxy nor have I gotten an e-mail with a code to redeem for it.

Same here. Apparently there is a slight delay: https://www.gog.com/forum/general/gog_summer_sale_2017/post147

Well just have to be patient. :)

Nothing so far.

Mine finally showed up. What's odd is it showed up after I made my second purchase from the sale, with the e-mail containing the code arriving less then a minute after the second purchase was made.

It was exactly the same here.

I still haven't received the code. Bought 3 items at the same time about 5 hours ago :(

Dito.
Bought Halcyon6 yet 4 hours later still nothing.

let me know if you don't get it. I'll give you mine.

Yeah, made a purchase around 6 hours ago. Still nothing though.
Should I just hang tight or contact support?

Edit: Just received it.

Thanks for your kindness, tinyE.
But this is a matter that GOG has to solve for themselves. And it seems I'm not the only one with this problem.

Just be patient. I imagine there's a huge backlog of codes in the queue that need to be sent. I made a purchase 6 hours ago and just received the code a half hour ago.

5 hours... but it´s good to know that it´s just because of a delay.

I made a purchase this morning as well and haven't received it but I am told patience is the key

I got an apologetic e-mail with the code now. FYI I haven't bought anything else since the first purchase.By the looks of the e-mail I wonder if they have to send these manually to everyone who didn't get it automatically.

Anyway, try to be patient if you haven't got it yet.

And thanks gog for the gift btw!

I can't redeem my Rebel Galaxy code because GOG used a "SkyNet" reCaptcha, which won't display in my secured traditionally installed browser, while I won't use any identifying accounts through my portable browser + portable proxy system.

I used this proxy set up to complete the reCaptcha (while SkyNet probed a node somewhere in the world) but, after that, GOG wanted me to log in, so I cancelled.

What can I do?

My contract is with GOG alone, is it not?

[i]The only "SkyNet" associations I allow anywhere on the web are YT top level domains and g__gl_video.
I don't allow any of their other background scripts on that site, nor will I ever use HTML5 video, which allows them to perform all sorts of covert tracking without the viewer being aware.
In the past few days I've noticed several videos I've tried to view on the site have some new "metrics" stuff in the background which, when blocked, send videos into an endless request loop, preventing me from watching them.
