Input: Consider Input: I had almost all of the Jean Auel's books and needed this one to complete my collection. It turned out to be a book club size and I traded it to a friend for the full size version.

Output: Positive

Input: Consider Input: Purchased from We Sell Bulk here on Amazon and received the item much faster than predicted delivery date - I only say that because there's always a list and it's often difficult to pick which seller is the one to go with. Anyhow, the battery came in original and undamaged Canon packaging (looks just like the images available in product description). I was not about to buy the cheap knockoffs and was worried that the one I ordered would be any different than the one that came with the camera (damaged item or store return). Well, after a couple charges and hundreds of pictures, I can say that this battery is exactly the same as our original. It lasts just as long and charges in the same amount of time. Our camera is fairly new so it was a fair comparison - one battery wasn't all that much older than the other.Email me with questions: mister_mr_d@hotmail.com

Output: Positive

Input: Consider Input: I had the movie before, but when I saw that the collectors addition had the "Flyboys Game" I thought I would buy it off the market place. Good seller, but the DVD did not come with the game as advertised. It only came with a DEMO version of the game. They should have said that on the box. Thanks a bunch for false advertisement. Thought the other extras might make up for it, WRONG! Don't waste your time or money.
Output: Negative
