My friend and I built a proof of concept to post books for sale that were not available on Amazon.com but were available on Half.com for a markup. When someone orders on Amazon.com, place an order on Half.com and change the shipping address.

were you able to make money using it ?

I personally know someone who successfully arbitraged Amazon and Half.com.

There is so much potential out there.

[misiti3780]

can you explain more about how the arbitrage works ? I am confused how it is possible. for instance, I buy a lot of used books from amazon.com (well, third party sellers). when i one-buy click, the purchase goes through immediately, and the sellar already has the book listed, so i am confused how it would even be done.

This is very easy and actually quite common between Amazon and Ebay. You would list the title as Merchant Fulfilled on Amazon and when someone orders it you would place the order yourself on Half.com using their shipping address and pocketing the difference.

To add to this, you can use Amazon Listing API to add/remove items that are available on Half.com.

how did you go about finding the items that were on Half but not on amazon though ? - manually ?
