Rodzaju: I have found a solution that works for me.
Every time I see a "Can't possibly refuse" promo on a game that I was perfectly happy to buy at full price, I buy it again anyway & run a giveaway!
That's a good idea. I just need to get to back to work again when I can to afford that. Of course, by that time, the promo will be over, but still, good idea.
Adzeth: I think that waiting for games you want (in a timely manner) to go on a discount when you've no insider information on when it's going down is kind of like gambling. You stake the contents of your free time (or if you collect soundtracks, playlist) on a chance to save $4 or less :p
You have an excellent point that I didn't think of. Though, I'm still waiting for Jedi Knight II to arrive and Thief Gold/Thief II to go on sale. :P
