You will never find a wholesaler that can help you sell dvd's on ebay. The wholesale prices are just too high to even consider making profits on ebay. Lets say the retail price on a new release is $19.99 That means the wholesale price of that same dvd is going to be $17.99
Walmart always sells dvd movies at $13.99 for a few days when they are released, This commonly gives people the misconception that dvd's can be found cheaper. And that wholesale prices on dvd's are somewhere around $9.99 .. This is absolutely not true. Walmart takes a 55 Million dollar a year loss on dvd sales and that number is growing each year. They do this to bring people into thier store. As you all know you cant walk into a walmart and get just 1 item. Especially if you bring your wife into the store with you. I go in there for a $5.99 item and my wife cleans out my wallet and poof $300 just exited my Rear End. :
This is common Worldwide. Also the massive amount of bootlegs on ebay severly hinders all of the legit sellers on ebay.
My advise is to get out of dvds and run while you can. Dvd's right now are horriblly unprofitable on ebay. Your fees will quickly kill any profits you may get.
If you are not a established dvd seller with a huge repeat bidder base then you better not even bother with it.
