ZenWan: Do the discounts expire each day when the new ones appear, or do they remain for the full sale period of 18 days, iirc?
I can't see anything in GOG's spiel about the discounts expiring, but it could, of course, be staring me in the face and I missed it...
CarrionCrow: The bundle deals change once a day, the single game deals change every 12 hours.
Figuring repeats will show up eventually, and bundles always get an encore day so everyone has a final chance to grab them, but for the moment, if something's gone there's no way of knowing when it will return.
Geralt_of_Rivia: The discounts expire. See the timer above the deals. The bundles expire every 24h, the other deals expire every 12h. When they expire they will be replaced with new bundles/deals.
Usually the bundles will repeat at least once but there is no guarantee for that. The same is true for the offers. So if you want to get something that is on offer now you still have about 7:30 hours.
Thank you both. I was looking at the sale page here
https://www.gog.com/news/the_2015_drmfree_summer_sale_starts_today and didn't see anything about discounts expiring, only about new ones being added.
But I guess that you are correct, that they expire when the new ones come up, or they could end up with just about everything on the site being on sale at the same time.
+1 :-)
