I still don't know how drop shipping works.

Many months in fact is last year I first come to know what is " Drop shipping " in Amazon and Ebay.

That means you buy low and sell high

Usually is they will search those niches are popular yet price is reasonable at Amazon than

list the product on Ebay to sell high.

I confuse is the transaction part.

Let say , I find one product in Amazon than I listed on EBay.

how I go about it?

Next I also read out Ebay charge some fee ...need to calculate the fee to minus the price of the product roughly estimate the profit ea per item sold.

Lastly when the buyer buy ....they will get to see is from Amazon as Amazon got their own package.

And buyer if they want to refund....also another headache part how to do refund?

that why I skip this drop shipping but I do know some IM is expert on this and enjoying doing as if you happen list many items on Ebay ..you will ea quite a good decent profits in the end.
