I got to tell you that I have searched high and low for this answer. I have tried many sites like Doba that I believe is a joke. Sites like these are over run by competitors and often to over priced.
I did run across a website that has tons of drop shipping companies based right in the U.S. To my surprise 99% of the drop shipping companies listed on their website I have never heard of. This means the competition of selling the same product for the same price as others is eliminated. I have finally been able to sell lots of items using this company. I have been using them for several months now and have zero regret.
Their drop shippers are verified and they do not consider companies like Doba that offer middlemen prices. Anyways, I hope this helps you out in your search for a great drop shipper to use on eBay. I have not had much time to really sell here on eBay but maybe in the future I will be able to.
If you want to know what company I use feel free to contact me. I simply do not want to list it here and run up the competition. I am sure you understand.
