Does anyone mess around with price tracker?

[Banger]

I tend to get extremely nerdy around October and watch endless amounts of horror films, so this year i've decided to keep an eye on a bunch of blu ray titles with the price tracker feature.

On my list, so far:


30 Days of Night
Cabin Fever
Child's Play
Children Of The Corn
Dawn Of The Dead
Dead Snow
Exorcist
Friday The 13th, Part II
House Of The Devil
Hostel
Let The Right One In
Monster Squad
Psycho
Piranha
Shaun Of The Dead
The Stepfather (original)
Trollhunter

The majority of the prices I want to see are about $10 and under with the exception of a few. Anyone else use this feature? If so, what are you tracking?
