This year Warner is charging less per exchange and is allowing you to trade in all of your used DVD's not just Warner Brother films.
Any DVD that is professionally produced content purchased at a regular retail or e-commerce store can be used (sorry no XXX movies).
The DVDs can contain film, TV, sports, animation or documentary content and can be from Warner Bros. or non-Warner Bros.
This year, it will only cost you $4.95 per Blu-ray movie and you get free shipping if your order is more than $35.
Sony's getting pretty desperate if you ask me.
