We could use a thread for that, because GDT will hit four digits soon and is quite cluttered :)

The story so far:
Gamersgate.com is having weekly sales and daily deals for four weeks.
Gamersgate.co.uk has the above, plus a daily EA game sale.
Steam so far offers yet another lottery - visit the page of the daily deal to enter a draw.
Basilisk Games is offering Eschalon 1 and 2 for half the price until the New Year.
Matrix Games is holding a big (for them) sale.
Origin is running daily deals.
Indie Royale Bundles have been announced for Christmas and the New Year.
Amazon Game Downloads service (US-only; similar to GamersGate in delivery system) is also having massive sales, plus rewards purchases with $5 coupons to spend during a later event.
DotEmu is offering variable sale rates on a ton of games until the New Year.
Book of Unwritten Tales is 20% off until Christmas + you get an extra 20% discount coupon for a friend.
24 Days that Matter - another lottery. Facebook or twitter accounts may enter the draw every day to win an indie game.

[s] GOG is waiting.[/s]
GOG strikes again

Don't forget the Indie Royale bundles - which are technically sales too!

On a different note, could anyone who has bought a Matrix Games digital download game clarify whether their installers are backup-able like GOG's or GamersGate?

Origin has a special Deal every day, but they always anounce them a week in advance.

You get the installer and the serial for it. No online activation.

Sounds like a great deal to me. I'm off to the Matrix Games webstore now :)

Bump. Any more holiday deals out there?

GG today offers Star Wolves 1-3 bundle (and Battlefield 2 Complete Collection UK).

Hey, you forgot Amazon deals for U.S. addresses! :)
I think they're rotating themes daily now, with select games going for up to 70%-80%+ off, and you get an extra $5 coupon for each of those listed games that you buy which you can later use to get discounts on 2011 bestsellers in January. Phew, long sentence.

(no longer available) The Witcher 2 Digital Premium edition is $15.99, and you will also get that $5 coupon to use later.(no longer available)

EDIT:
OK, scratch that, Witcher 2 sale is over now.. Hopefully GOG does a sale for it next year when I have a stronger PC.

Amazon linky is here. Today is Strategy Day:

Rome: TW Gold is $2.50
Shogun 2 is $9.99
Sword of the Stars Complete is $4.99
Majesty Pack is $7.46

You get $5 codes for these, too!

No, we try to ignore it ;-P

Which is fascinating because IV bundle isn't over yet.

Yeah, and with 4 days remaining, i wonder if they are going to reach 1 million in payments.

There's no snow here.

No snow = no winter.

No winter = no winter sale.

Maybe GOG should be compared to other similar, ie. DRM-free, services.

I went to check DotEmu, but I didn't see any blinking lights with grazy "90% off" deals either. What's up with that? The last news I saw there was about the earlier weekend promo.

Any others, e.g. what was that DRM-free indie game publisher (I don't recall the name), do they also have some daily deals now?

Or is it only the DRM sites which carry grazy deals now?

Dotemu got overcome by the selling spirit.

Added Book of Unwritten Tales deal.
