Honestly, if you knew about the blu-ray format and the capacity 1 disc has you should be appalled that there isn't the entire peanuts collection on 1 disc. This is such a obvious marketing plot to extort more money out of the consumer. If you buy this disc you are only feeding into that disgraceful behavior. If you don't know, blu-rays can hold more than 10 times the amount of content a DVD can hold. The entire peanuts movie collection can fit on to one blu-ray disc and to seperate them over 10+ discs just takes more money from you to send their fat kids to college. A pox on both your houses.

Ex Output:

After reading all the great reviews on this product on Amazon, I decided to go for this. I don't typically have good results from diet products, but I figured I'd give it a shot. I've been taking these for 3 weeks, as directed, and I might as well have been taking sugar pills for all the more this is doing for me. I felt like my appetite increased, I haven't lost any weight at all - in fact I've been fluctuating up and down 3 pounds for the past couple of weeks. I gave this two stars because I didn't feel the anxiety or sleeplessness that some people complained about, but I'm still disappointed. I was hoping I'd find something that actually worked!

Ex Output:

As any fan of Nirvana is well aware, Kurt Cobain had a fear that was close to outright paranoia about Nirvana's music being milked and exploited to make a buck. All of a sudden, that fear seems totally legitimate.This is (basically) the 3rd "Greatest Hits" cd that's been released under the band's banner. Nirvana only had three studio released cds. Well ... four if you count 'Incesticide.'If you're a younger fan and you want a terrific introduction to the band's work save your money from cd and save up for the 'With the Lights Out' box-set. It doesn't cost too much and is a great way to break into the band.A true Nirvana fan understands that the only meaning behind this piece is dollar signs.
