F4LL0UT: Oh yeah, would love if the algorithm first determined a user's price range and then picked the right deal for him.
"Oh, this one's a rich fart - okay, the Entire GOG Catalogue 90% off! Sorry, for technical reasons you also have to pay for the ones you already own but we *know* you can afford it."
Not such a problem for some, but I got one offer for the Jetpack Dragon game on the first day at the same price as it was in the daily sale that day. It would not be so bad if I had been looking at the game as a near future purchase, but for not even an extra 1-2% off the price it rather missed the mark when others are getting 75% off of the latest Shadow Worrier.
Added to which is I only spend more then $10 on games I MUST own (NWN2 / H:BM). On everything else I can wait until it is at a price I feel is appropriate for the game.
Just look at Fallout, I already own them twice and felt that $10 individually was a bit much for a third time, so Interplay met me on my terms and gave them to me (and everyone else) for free.
