Couldn't find my answer anywhere, so my question is does gog ever repeat daily bundle sales during the summer sale? I was interested in the D&D bundle that was on sale the other day but didn't have the money for it at the time. Is there a possibility that it will appear again while the sale is going on or am I out of luck?

I remember they doing an encore or something like that for the bundles in a similar sale before.

AFAIk, the last day of their holiday sale, GOG makes a big whole page full of all the bundles that went through.

There is no guarantee for a repeat but GOG often has a day during the sale on which you can buy all bundles that show up during the sale.

@koima57: That's not always on the last day.

On top of that the -80% for all D&D titles isn't really new. That bundle usually shows up several times a year.

Similar question: Do you think any of the games in the bundle will be discounted lower than the individual prices? I don't want to buy all of them, but I don't know if being in a bundle excludes them from the flash sales.

We don't know which games will show up in bundles in the course of the next 2 weeks but it is well possible that some of them will be otherwise reduced during the sale. This sale consists of three parts:

1) Most of the catalog is reduced by 50% during the whole sale.

2) There will be two bundles each day. We don't know which games will be in the bundles or how big the price reduction will be. And GOG won't tell. :-)

3) Daily Flash deals: Single games from a specific pool of games come up randomly an will get a pretty high reduction for 2 hours. The games from this pool are already known. See this thread for a list of what has already come up.

If past sales is anything to go by, you're not out of luck:

~1~ Holiday (Winter) Sales 2012

Day #15: Dungeons & Dragons Deal
Day #22: One promo to rule them all, i.e.all promos offered, D&D one included


~2~ 2013 #noDRM Summer Sale

Day #1: Definitive Dungeons and Dragons bundle
Day #17: Summer Sale Finale - all bundles & promos offered, D&D one included


~3~ 2013 Drm-free Winter Sale

Day #4: Dungeons and Dragons Desire
Day #7: 2013 SOLSTICE FESTIVMAS - repeat of the offered that far bundles, D&D one included


So, there's a good chance that the daily bundles will repeat at some point.

Yes, they have done that in the past, usually an encore at the end of the entire promotion, either on the last day or one day after however it is unannounced and no guarantee they will do it every time. They've occasionally done an "incore" I'll call it, which is like the encore but happens in the middle of the promo period (ie: The End of the World Sale on Dec 21, 2012 in the middle of the winter promo). They may also repeat individual promo bundles randomly from time to time too.

Basically anything is possible, and there is precedence but no guarantees and no way to know for sure unless they do it or announce it in advance which normally doesn't happen. :)
