I just checked out the new video store in my neighborhood, and was blown away by their selection of pre-viewed DVDs. They had a ton of titles I wanted, and they are all two for $20. So the burning question is...Why should I not buy used DVDs? I bought two just to see what I'd get, and here's the lowdown, They come in original box, 1 small sticker on front of box that is easily removed. The store offers 90 day return policy. The little booklet is missing from inside cover. Are there any good reasons not to buy these things? I did a search and didn't find much, but was still wondering if there are things I need to be aware of before going and dropping 2 Bens on DVDs. Do these rentals have previews, while new ones would not?
