Does anyone use amazon for dropshipping their products,for an ebay store??

You cannot use Prime to dropship products to your customers. Amazon doesn't allow it. You can try it, but once they see what you are doing, they will close your account.

A better option would be to use Amazon's FBA program, and fullfill your orders from FBA, its called multi-channel fulfillment. They will store your inventory and ship your orders.

As a full-time seller on both Amazon and Ebay (for over 5 years) I am very familiar with selling on both.

I would also suggest subscribing to Skip McGrath's newsletter:
FREE Newsletter for Professional eBay Sellers

It has tons of useful info, its free, and he shares wholesale/dropshipping companies in every issue.

True, perhaps.

But if you going to be doing dropshipping to US customers I would strongly recomment that you deal with American-based distributors and wholesalers.

You're going to suffer a whole lot of grief trying to dropship items from companies outside the US.

For one thing there's the time delay. In my experience customers expect their order to arrive next day? Of course we know this isn;t going to happen but bear in mind, with online retail customers do expect tor receive good quickly. Importing from overseas takes longer and the time-lag from ordering to receiving the goods is going to annoy most of your US customers.

Also, you'll be importing goods from outside the US and therefore you are going to experience problems with US customs. While this could be manageable when ordering large amounts of goods, dealing with issue like this on an order-by-order basis is a recipe for disaster.
