Hi Leanne,
I couldn't really find any information about dropshipment on Amazon although i read about it on a few forums.
I did find information of Link hidden: Login to view. Which basically means that With Fulfillment by Amazon (FBA) you store your products in Amazon's fulfillment centers, and once your product sells they will pack, ship, and provide customer service for your products.
I'm not sure if you are referring to Fishpond.com in your question, if you are please confirm. If not, please provide us the complete URL so we can check it out further.
All the best :)
