Yes, I'm doing this again. Because I'm bored. And the timer doesn't care when I scream at it. And I hate myself sometimes.

Posting this, then adding, just in case someone gets the same self-loathing riddled idea of doing it at the last minute.

All prices listed are U.S.-based. Regional pricing may apply to your area.

If I get something wrong, please let me know. Frequently can't see higher prices for bundles since only the deeper discounts show for me.

For further in-depth information, feel free to check out RWarehall's sale tracker spreadsheet here.

Scroll down for additional day lists.

Okay, the forum's trying to break, currently stating this has negative one replies. Now attempting to boot it in the ass so it works properly.

Now it says there are zero replies, saying this is page zero. Lovely.

Looks like it is working for me :D

Between my reply and yours, it seems to have kicked the forum error, moving it from negative numbers to positive ones. Thank you. =)

Perhpas we should convince the squirrel to steal the forum bugs instead of the gifts :D

Either that, or get them to take the katana to the aforementioned problems. Might be a more permanent solution.

Thanks for posting. I love these threads.

I did put together a spreadsheet this time around:
GoG 2015 Big Winter Sale Tracker

You may feel free to link it in the OP if you wish.

You missed a few "unadvertised" deals:

Days 1 & 2:
Divinity: Original Sin – Enhanced Edition - 33% off $26.69
Dreamfall Chapters Season Pass - 60% off $11.99
Dreamfall Chapters Season Pass – Special Edition Upgrade - 60% off $3.99
Gods Will Be Watching: Special Edition Upgrade - 60% off $3.99
Shadowrun: Hong Kong Deluxe Edition Upgrade - 50% off $4.99
Stasis: Deluxe Edition Upgrade - 50% off $7.49
Titan Souls: Digital Special Edition Upgrade - 66% off $1.69

Day 3:
Kyn – Deluxe Edition - 75% off $6.29
Toren Deluxe Edition - 60% off $5.19

Gotta love it when the site running the sale doesn't let you know chunks of what's on discount. Thank you for the info, will add that to the list.

Thanks Crow and RWarehall,

List is updated, and your spreadsheet is now linked to. Thank you. =)

Thought about doing this yesterday, but when I saw RWarehall's spreadsheet that he linked to in one of the other threads, I figured I might as well not bother. =D But have fun, I suppose; at least this thread will more easily be found in a forum search down the road than a single post in some other thread would.

+Rep to you both, of course. =)

Thank you, CarrionCrow, for starting this thread! I like this format more than a spreadsheet. +1

Thank you, RWarehall, for your efforts, that spreadsheet is ridiculously detailed, and I'm sure a lot of people will find it much more useful, but I prefer the simpler forum styled tracking thread. +1

I also appreciate the daily tracker. The spreadsheet history derived from the rotating Flash sales and predicting what sales would come next. I don't see the point in repeating what is already here.

Todays only stealth upgrade:
Republique Deluxe Edition Upgrade - 50% off $4.99

I find the spreadsheet good for two things:
1) Seeing if the game you want has been on sale (and how)
2) Predicting which bundles may come up next by looking at the games not on sale yet.

Also added a new feature, a second tab with the sales arranged by type.

It is up to date as well...
