Query: Cinderella

I purchased a two disc DVD set of the movie "Cinderella" (used). The one disc was said to have a scratch, but would play just fine. However, when I tried (several times) to play the movie, it would play about 60% of the movie and start over each time. I reported the problem and was informed right away thet my credit card was reembursed with the full purchase price.The point of this reviews is the fact that Amazon.com and "Lets watch a movie" stood behind their product and did not hesitate to correct the problem. This gives me confidence that even if things go wrong, Amazon.com will stand behind their product and do thre right thing for their customers.
