Sale Prices vs. New Prices

[WyldeMan45]

I love the latest price drops tracker at the top of the site, but I am never sure what is a sale price for the week, and what is the new price. Is there any way to tell, besides checking the best buy ads? There are some which you can tell or already know it's just for the week, cause you've come across the info, but what about films like The Green Mile? I couldn't find anything specific about it being a sale item, but $8.00 seems like a huge drop. I'd love to have this movie, but with buying so many others in the upcoming weeks, I'm not sure if this is something I must buy now to get the price, or if it'll be the standard new adjusted price from now on. Any help on when to know whats new and whats just a sale would be greatly appreciated.
