Sales on GOG:
First and third wednesday in the month: one game for 50-60% discount.
Every weekend if there are no other big announcements going on: 3-6 games for 40-60% discount.
Summer sale: 2-3 weeks in july about half the catalogue with 30-50% discount.
Christmas sale: approx. one week before christmas til start of january virtually the whole catalogue for 50%.
Rare but happens: Permanent price drops for older games.
That can be expected for this year again.
I too only bought games on sale lately. The backlog is too huge not to wait with wishlisted games. After all I might never be able to play them.
There may be a few other sales than the ones mentioned above--I have to justify to GOG.com why they keep me around, after all--but if you check out the main page every week or so you won't miss out on anything extra.
