Web page looks nice , good luck.
I have sold DVD's on Ebay and it is so competitive , some vendors prices are so low it seems the only way they make money is by selling in large volumes.
Because I have worked in Video rental business I know that Wal-Mart on Movie Debut Tuesday is usually still cheaper than the distributors we ordered our movies from , so when I started selling DVD's I bypassed the distributors and went straight to the manufacturer , ALOT cheaper only problem is you must buy in large quantity , which is fine if they have a large catalog of films . You just can't compete with a Giant like Wal-Mart , you'll have better success with specialty DVD's like HD or specialized Genre movies.
It's a tough business , I wish you the best of luck.
