I've lucked out not once, not twice, but thrice!
First I got in on the Clone Wars/Testris deal. I remember going to CC and there were seven left. I bought two. A week later, after I had publicly posted that there were some available at that CC, I went back to see the new weeks deals and decided to check if any were left. All five were still remaining, so I bought three more and left two. The next week those two were gone.
Then I also got in on the Sims Deluxe deal. Where if you buy Sims for $19.99 you get a $20 gift card. I ended up buying three. One for myself, one for my sister, and one for future gifts/trades. I ended up using the $20 gift card to get Dungeon Seige and MoH:AA. Since I would have bought those anyway, Basically I got three copies of the Sims Deluxe for a peny each. (CC charged $20.01 when I bought the sims.)
Finally, about a month after I posted the penny EA Gamers Pack deal at BB on CAG, I was in BB looking for PS2 games during their clearance. As a lark I decide to do a once over of the software isle not expecting anything. But low and behold, on the bottom shelf was one copy of the EA Gamers Pack. One that hadn't been there a month ago so it was obviously new stock. Only had one, but it rang up a penny. I still recall the astonishment of the cashier when this rang up for one cent and Dynsasty Tactics 2 was $9.99.
But I'm still pining for that copy of Fatal frame 2 for $9.99.
