I bit on the $20 Hitman Trilogy deal recently and ended up getting it for $0. Amazon turned around and e-mailed me a $5 promotional credit, strangely. I'm considering using that toward this to subsidize the purchase down to $15, then applying Bing points for the difference. S&H is always a problem with me, though; I may not order because I need some filler to bring the order total to $25 for free S&H. Hmmmm...
CORRECTION: The $5 credit is for digital video game downloads only, which for 360 is pretty much useless. At $20 plus S&H, I'll wait for the inevitable $10 via Gamefly deal. I haven't played Hitman at all save for a demo on the PS2 10 years ago, so I'm in no rush to get to Absolution.
