Nah, Steam has deals fairly regularly. There's always a 'midweek madness' sale where you can often bag some pretty good games for the same price you'd get them on the holidays, and occasionally good weekend deals too.
Then I recall there was a random big sale that went on last summer as well. Keep an eye on it.
However, gog.com is honestly more worth your attention if you like old games. I support that website wholeheartedly and IMO their business model is the fairest to the customer (what with the no-DRM policy and no-hassle distribution)
