I didn't find it "easy" to get approved for DVDs. I had over 20k a month in used media sales for over 12 months and still got rejected. The worst part is that you can buy the media, ask for approval, and then get stuck with the inventory. On top of that what you buy from a distributor will never make you any money. It's all in the used items so you hope to make it up by selling DVDs you buy for a dollar at library sales, etc.
It just doesn't have the ease of FBA. We were primarily used book sellers and occasional video games. Unfortunately, while I was incarcerated my partner blew up the business.
