There's advantages to drop shippers:
1) you dont have to invest in inventory
2) they do all the shipping for you
But disadvantages are:
1) they control the price of the item
2) if there's a dispute between the buyer and you and merchandise has to be returned, do they ship it back to the drop shipper? How do you know the item's messed up if you've never seen it?
3) You're paying them fees for the service that you could be paying yourself
You ever sold stuff on ebayed anything before? If not, buy some cheap stuff and sell it on ebay, used DVD's, CD's, whatever, start getting your feedback up, learn the many ways to ship, get a scale, Priority Mail and non PM boxes, hoard plastic peanuts, etc and dive into for a couple months
I just sell my own stuff, if you want to make money, invest some $ into inventory you can move, in the other thread it was knives and holsters.
