The system is simple enough, and allows you to even copy and paste the listings they have straight into your listings on eBay.
However, the prices for the items are a bit less than competitve than those that are currently selling on ebay. Additionally, checking over the prices offered on ebay, its curiously strange that you have a multitude of sellers selling at the same cost price you can get it for on Doba.
On the upside, the database is of considerable size, and you can spend many hours searching through the categories and although the effort is visible,the navigation still requires some fine tuning.
You can find things on DOBA to sell and make a profit, but its going to take work. Not on listing the item, but finding an item that you can actually make a profit from.
